Well, here's another fine mess you've gotten me into
Attributed to Oliver Hardy, and often said after another one of Stan Laurel's mistakes.
The actual quote was "Well, here's another nice mess you've gotten me into!", which was said in the 1930's short The Hardy Murder Case although there were several variations in subsequent films. The short which followed The Hardy Murder Case was Another Fine Mess, which is presumably the source.
Ray Stevens later recorded a song that quoted "Here's another fine mess you've gotten me into / another fine mess, ah well, what else is new."
