So many great lines and great court scenes but I also love a couple of the little side stories and tangents.
For example:
1. the lack of sleep from the roosters, then the train whistle, asking the front desk guy about the train coming through and him saying it was very unusual, then it does it again, him dinging the bell constantly and then the guy saying it usually comes through earlier, then trying to sleep in the woods, getting spooked and shooting his gun, and finally telling Marisa to leave him in jail so he can get some sleep and he is peacefully asleep to the constant noise of a jail.
2. Collecting the bet from the pool hall guys, how he doesn't have the money, the whole "oh that's what we call a counter offer... lemme see either you kick my ass now OR..." then the guys rolls up ones inside a 20, until he finally has it and then he more or less sucker punches him. Although that was one of the most awkward film punches from 5'1" Vinny to a 6'5" giant. but it was funny.
3. the constant run of jokes about his wardrobe.
Just great stuff on top of all the main plot.
