Tonight's Picks: Thursday, May 22

"So You Think You Can Dance" returns to the airwaves tonight with Cat Deely back to host. Tonight's an auditions segment so expect plenty of pratfalls and insanity along with the good moves.

"Ugly Betty" season finale finds the gang squaring off against Naomi Campbell and Elle magazine in a softball game. And Lindsay Lohan guests in a role that is supposed to resume in the fall.

Season finale of "Grey's Anatomy" marks the unofficial end of the television season. And the big question on tonight's episode is...how do we get that dude out of that block of cement?
