For those who were not there, the amount of time it took Mick to jack up the car (seven verses per half inch - why is the song so short?) had to do with these facts:
1) The jack was crappy
2) Mick would not let anyone help him. He wanted bragging rights, and also the right to Give Me Shit throughout eternity. A Shellback or two offered to spell him, but Mick just kept on cranking...

Where is Noreen and the song she wrote down? I think she ought to post it soon, as I'm about to begin speaking in double entendre.
