Only because he gets his c*ck out. It was posted earlier but Coke really does work. My uncle was a marine engineer, one day in dry dock the were trying to remove a propeller from it's shaft. They had huge pullers, super heaters etc on the job without success, a Yank passing the dock shouted "I'll send you something that will get that off". Half an hour later he turned up with a couple of crates of Coke. The lads thought it was to drink, he said pour it over the shaft/shaft and leave it for 12 hours. It popped of like a cock in a three cornered hat.
