Two weeks ago, on an episode of "Curb Your Enthusiasm":

Larry is on an airplane whining about how long his shoelaces are. After a trip to the restroom, he accidentally trips over the laces, falls forward, and knocks over a large man who was about to beat-up one of the stewardessess. (The big guy is drunk and she refused to serve him any more liquor.) The big guy begs the totally confused Larry not to beat him up, and skulks back to his seat. Larry is proclaimed a great hero, the toast of Manhattan (where the plane was heading), and wins the heart of the girl seated next to him.

Sound familiar, FKB fans??
