Ryan Lochte plays a sex idiot on " 30 Rock" and hopefully not anywhere else. The Olympic swimmer will guest star as himself in the Thursday, October 18 episode of "30 Rock" (8 p.m. ET on NBC).

In the NBC comedy, Lochte will play the "sex idiot" of Jack's (Alec Baldwin) new lady love. Here's how NBC describes the episode:

Liz (Tina Fey) works to prove to Tracy (Tracy Morgan) that women are funny while simultaneously attempting to head off a meltdown from Jenna (Jane Krakowski) after some negative publicity. Jack tries out an unconventional dating strategy.

"I get to play myself, I get to play just Ryan Lochte, so it's not too much acting that I have to do," Lochte said in an on-set interview. "So that's pretty good."
