When Mike Singletary dropped his pants at halftime against the Seattle Seahawks, the Hall of Fame linebacker became the butt of the national media's jokes.
But he probably never imagined that David Letterman would pick up on his act and rip him another hole with a regularly seen sketch where the San Francisco 49ers head coach looks like a complete fool on Letterman's show.
Since the Halloween week scare that Singletary dropped in the 49ers locker room, Letterman has aired a series of mock interviews with Singletary, where you see the overly excited, and may we say the incredibly loud, coach yelling about nothing and everything at the same time.
We have two of the interviews below. See if you can make out what is going on in the first one and let us know what you think.
