Triumph the Insult Comic Dog Visits the Set of ‘This is 40′

Over the years, you've seen Triumph the Insult Comic Dog on Conan O'Brien's shows but now the man behind Triumph, comedian Robert Smigel, has a supporting role in Judd Apatow's 'This is 40.' And, of course, Smigel brought Triumph along and had him talk to the cast of the film including Paul Rudd and Megan Fox. Hilarity ensues.

So what happens when Triumph the Insult Comic Dog visits the set of 'This is 40?' Well you get people like Apatow, Paul Rudd and Leslie Mann who seem to be very much in on the joke. And then you get people like John Lithgow (who looks frightened) and Megan Fox (who looks upset). But no matter who you get, it's funny.

We don't want to ruin the jokes here, but some of the best bits are when Triumph interviews Apatow and gives him grief for a) 'Funny People' and b) how long his movies are.

'This is 40' opens on Christmas and you can get yourself ready with this hilarious new Triumph the Insult Comic Dog video below.
