It seems Trump fatigue is already setting in. After a two-and-a-half-minute rant about reasons he doesn't think Donald Trump will run, MSNBC personality Lawrence O'Donnell was trumped himself — by his own guest.

Melissa Harris-Perry, after sitting through O'Donnell's tirade about Trump's ego, net worth and political savvy, immediately responded by laughing and saying, "We need something new to talk about, Lawrence."

This segment originally aired as part of Lawrence O'Donnell's Last Word on MSNBC, April 22, 2011.
