“The Simpsons” (8 p.m., Fox): Football legend Joe Montana drops by “The Simpsons” tonight, playing himself. He runs into Bart during a party being thrown to celebrate Lenny’s winning of the lottery. Indeed, anything can happen in Springfield.

“Mad Men” (10 p.m., AMC): Only two episodes remain in this season of the Emmy-winning “Mad Men.” Tonight, an old friend and Don renew acquaintances and Pete’s personal problems impact a major account.
