Last night, Bridesmaids' Melissa McCarthy visited Late Night with Jimmy Fallon to discuss the Emmys pageant bit she did with Amy Poelher, Tina Fey and the other Best Lead Actress in a Comedy nominees. She also recalled the time when she had an eventful conniption in the middle of a discount furniture store (with a very catchy slogan) after she found out she was going to host SNL.
Chaz Bono appeared on The Tonight Show to talk about Dancing with the Stars (and his rigorous training for it), and how he deals with all the ignorant remarks about his appearance on the show is "influencing children toward sex-change operations."
Also on The Tonight Show, Albert Brooks had a lot to say about how technology is changing society—it's turning people into hypochondriacs, co-dependents, and addicts. He also thankfully shared his theory on what would happen if you gave a shark and iPad.
Finally, South Park creators Trey Parker and Matt Stone stopped by Jimmy Kimmel Live to talk about the emotional rollercoaster of taking acid (and wearing dresses) before attending the Oscars as nominees for their South Park movie.
