Episode 19 of "Ally McBeal"
s01e19 Happy Birthday, Baby

Ally is in denial about her birthday but her co-workers aren't. Elaine orchestrates a party at the bar and asks Dr. Greg Butters to sing a romantic ballad dedicated to Ally. He does, and knocks the socks off everyone in the room. Renee is especially moved, and jumps up on stage to join him in a seductive duet. Meanwhile, in the courtroom, Ally is forced to take the position for a new client that his foot fetish qualifies him as temporarily insane. Renee, as the opposing district attorney, maintains that sneaking into a would-be date's apartment uninvited to tickle her feet is breaking and entering.
