A funny joke

So it was the 1600's and there was this job where you had to ring this giant metal bell every important hour like 12:00am, so the guy got too old to do it and this monk volunteered to do it, but he had no arms so he rang the bell with his head.Two days later he was found dead with cuts and bruises on his head, the building owner found is body and alerted the police, when they arrived the building owner said to the police man "do you know this guy?" He replied "No,but his face rings a bell" [spoiler]ba dum tssss...[/spoiler]
