The most decorated Olympian in history will play himself on the episode, scheduled to air at 9 p.m.
Phelps' IMDb page also includes a 2008 appearance on HBO's "Entourage" in which he played, you guessed it, himself.

A representative said Phelps wasn't available for an interview this week.Copyright © 2015, The Baltimore Sun
