With so many niche charitable causes for celebrities to choose, how could you possibly pick just one? In his new PSA, Saturday Night Live alum Kevin Nealon goes for sheer quantity, tackling everything from infantile baldness and bulimic insomnia to out-of-work astronauts and texting while scuba diving. Bad news for the night vomiters, though: It's actually just an ad (made by TBWA\Chiat\Day in Los Angeles) encouraging pet adoptions and neutering. "There are a lot of problems out there, and unfortunately we can't do much about a lot of them," Nealon concludes. "But here's one you can do something about: homeless pets." Sure, it's pretty funny. But what about all those scruffy ex-astronauts panhandling down by the car wash? You could have been their hero, Kevin. Via Copyranter.
