When, towards the end of the film, Benny and his gang are (again) chasing Alfred through the woods, the victim is wearing a sleeve-less top. However, by the time they throw him in the lake, it has become a long-sleeved jacket. When he is under the jetty the jacket is seen to have dark cuffs.
But when he emerges from the lake and approaches Benny, he is wearing this same brown jacket. Only now it, and the rest of his clothes, are bone dry and nicely pressed and he has not a hair out of place.
