Toothpick Hairdo Prank
These fellows might have always dreamed about some kind of practical prank regarding this guy's hairdo.
Well, some warm, late summer-party night their wish became true and old Hans here passed out without a clue.
Could well be that his friends not only always hated the way all the girls admired the curls and wanted to play with them, most likely the Norwegian blanky as much as his strong Scandinavian accent bored the hell out of everyone.
As a next prank his colleagues want to lock him up in a sauna with a real reindeer for a week. Maybe he can teach the animal to play Mikado with the tooth picks then.
