It's tasteless, yeah. But it's comedy. It's hard to say there are limits.
[edit] It was 18 days after 9/11 at the Friars club roast of Hugh Hefner
Also, I recall a celebrity had a dead crocodile hunter costume for Halloween (Irwin died in September).
[edit] It was Bill Maher.
So it didn't fly?
That's a perfect example of a comedian taking something supposedly solemn and turning it funny. Kind of like when a chef takes an off-cut of meat and turns it into something delicious.

For example, I just searched Google for "comedian pedophilia joke" and the first result is about Louis C.K. doing one during an SNL monologue.
Nothing is off limits in comedy. Plenty of stuff is in bad taste, but as long as the comedian is actually trying to be funny I think most or at least many other comedians will back them up.
