Last night, Johnny Depp visited The Late Show to tell a haunting story about summoning Justin Bieber by professing himself a ""Belieber.""

Justin Timberlake showed up on Jimmy Kimmel Live! to talk about the ""grace period"" of not showering, walking through Comic-Con in an Ernie costume, and then to dissect the mental problems/personality disorders of some of the Sesame Street characters with Jimmy.

Kal Penn visited Late Night with Jimmy Fallon to talk about leaving the White House to do a ""stoner movie,"" and all of smoke clouds and bodily fluids that will be availed to audiences in 3D in A Very Harold and Kumar Christmas.

Finally, Hugh Laurie appeared on Conan to talk about what a huge waste of time he thinks House is (at least as opposed to being a real doctor), his hobbies of fighting small children and drinking, and why he thinks long lifespans aren't necessarily a good thing.
