Comedian types are always pretty quick to dish it out, but the question always remains whether they themselves can take it. Enter the trusty Triumph the Insult Comic Dog to find out.

Funny or Die took the mean-spirited faux pooch to the set of Judd Apatow's "This is 40" to haggle him and his central cast — including Paul Rudd, Leslie Mann, Megan Fox and John Lithgow — to find out just how thick-skinned these supposedly funny people are. The appeal of Triumph, of course, is that he gets the jabs in nice and deep, and it's up to his victims to play it cool under the heat of his hateful barrage. 

So, how did the "40" gang fare? Well, Rudd got the worst of it when Triumph outright trivialized his place in the business of comedy by declaring, "I always like to follow your career because I love knowing which movies Zach Galifianakis turned down. Let's be honest, you're like the fourth guy they call right? I mean, when you can't get Will Ferrell or [Steve] Carell or Zach, then you call Paul Rudd and you say, 'Paul, do you have Danny McBride's phone number?'" Yow!

Also, Apatow was at the receiving end of the equally stinging inquiry "Is it pronounced Ap-a-tow or Crap-a-tow?" and Lithgow was downright informed he's a "freaky looking guy."

You know, there's a reason they call him Triumph. Win!
