Quote from Barney in The Rehearsal Dinner
Barney: And that was the end of it. Until my bachelor party. Security Guard: Uh-oh. Let me guess. There was a stripper. You had a little fun. Maybe took some ill-advised pictures. Next thing you know, she's blackmailing you into bankruptcy, And your medical degree's hanging on the wall of a laser tag security office! Barney: No.
