[Joe is at the Griffins' house, making his friends dance with hip. Cleveland is on the piano]
Joe: All right, we're gonna do it once more! [everyone moans in agony] And this time, NO MISTAKES! ONE, TWO, THREE, FOUR!
[Cleveland begins playing, while Peter, Joe and Quagmire dance]
Peter, Joe, and Quagmire: Good mornin', good mornin'!
Cleveland: It's great to stay up late!
Peter, Joe, and Quagmire: Good mornin', good mornin', to you!
[Joe sits on Quagmires lap as Peter continues dancing]
Peter: When the band, begins to play, The stars were shinin' bright!
Quagmire: But now the milkman's on his way, It's too late to say good night!
Joe: [shouts at Quagmire] SO SAY GOOD MORNIN'!
Quagmire: AHH! [starts sobbing] Good mornin'! [everyone continues dancing] Sunbeams will soon smile through
Peter, Joe, and Quagmire: Good mornin', good mornin', to you!
[the song ends, but Stewie pops out from behind the couch and continues by himself]
Stewie: Nothin' could be grander than to be in Louisiana! In the mornin', in the mor... Oh, I'm sorry, I thought we were still going.
