The stupidest thing he ever did was have fake sex with his boss with that nerd in his pants and leave him in there and then take him out a few hours later in the bar and the nerd almost died :(
Buying the helicopter and crashing it on his front lawn! That was epic! Also, the time he, Cleveland, and Joe hijacked an máy bay, máy bay chở khách to get Quagmire his job back.
Hmmm....There is the Surfin' Bird episode, then there is the time where he and Lois where gonna get it on and Peter shoved a dưa hấu in Lois's face..,well thats all i can think of.
