television & film
Above L-R:
i. Jon presents / acts / gets beaten up by the SAS in various TV programmes. It's Jon's showreel.
ii. Appearing on the noted terrorist network Al Jazzera, Jon goes up against David Frost in the inteviews that provided the basis for the multi award-winning film Frost/Holmes.
iii. YouTube clip of The Now Show where Jon deals with earthquakes and a startled cockatoo. Not strictly TV at all. And They've spelt his name wrong.
television
Jon has appeared on various TV shows that no-one ever saw and, if they did see them, probably di
dn't like them. For instance he once presented the Channel 4 late night comedy The 11 O'Clock Show which led to worldwide fame for Ricky Gervais, Mackenzie Crook and Sacha Baron Cohen. Jon's whereabouts are undetermined.
After that Jon went onto BBC3 to present little remembered satire show The State We're In alongside the now very successful Sharon Horgan of Pulling fame. On this show he threw a teddy bear at a nuclear power station, singlehandedly took on the Triads and got threatened at gunpoint by soldiers who put on a hood over his head in a deserted aircraft hanger and then pissed on him.
Jon also co-created the long running (but now gone) multi-awardwinning show BBC2 show Dead Ringers. It began life on Radio 4 and then transferred to TV, where it wasn't as good.
In 2007 co-wrote Armando Iannucci's Time Trumpet for BBC2. Look, there's a clip over there. To your right. Warmer.. warmer... there. He also worked with Armando on Gash which went out on Channel 4 every night for a week in the run up to the local elections. Channel 4 turned down series 2 because it “didn’t make the right noise for Channel 4”. This leads Armando to conclude that the right noise for Channel 4 is that of Vernon Kaye having his testicles attached to harrier jump jets that then fly off in different directions.
Jon was also asked to be stuck in the jungle to eat spiders with Ant and Dec on I'm A Celebrity Get Me Out Of Here. He told them to sod off. Jon is also the voice of BBC3's 7 Days and Crash Test Danny for the Discovery Channel.
Jon has also since appeared on, written or had to wear an uncomfortable wig for Dead Ringers, Have I Got News For You, Mock The Week, V Graham Norton, Harry Hill, The Impressionable Jon Culshaw, Armando Iannucci's Gash, a thing about Heroes and some other things that have since been axed or cancelled. See Jon's biography and CV for more. 
He also crops up on Sky News from time to time reviewing the papers and trying to make the presenter giggle at inappropriate points. He's also graced the This Morning sofa as Fern Britten and Phillip Schofield’s guest on ITV1. He sings happy birthday to Phil (it is Phil’s birthday) and then tells him (Phil) on live television that he (Phil) should be burnt as a witch. He is not asked back. he's also been on The Wright Stuff a fair few times but then, who hasn't?
2009 sees Jon working on a TV adaptation of the Horrible Histories books for BBC1 and a new Friday night comedy show for Jon Culshaw. Plus there are two, if not three, sitcoms in development along with an animation project. All are destined to be turned down by a variety of broadcast networks sometime later this year. 
Film
Jon is currently developing a film script with an undisclosed title for an undisclosed sum for an undisclosed company. That's not very helpful is it?
He's also written Stephen Fry's script for the BAFTA Film Awards where he drunkenly told Christian Slater that Broken Arrow was rubbish.
In other film news Jon has recently seen The Curious Case of Benjamin Button, In Bruges and Exit Wounds starring Steven Seagal. He has yet to watch Hellboy II: The Golden Army.
Other
Believe it or not Jon actually hosted the MOJO awards, possibly because they rang him by mistake. At dinner Jon sits between The Edge out of off of U2 and Ray Davies who tells Jon that he’s a big fan of his Radio 2 show The Day The Music Died. Jon can’t return the compliment because out of the entire body of The Kinks back catalogue, he only likes Waterloo Sunset if we’re honest. Then, Slash out of Guns n’ Roses gives him a hug that smells of cigarettes and modulated guitars and the rock and roll party hangover takes approx a month to get over.
