A church's bell ringer passed away
A church's bell ringer passed away, so they posted the position and a man came in with no arms wanting the job. The clergy weren't sure he could do it, but he convinced them to let him try it. They climbed the bell tower and the guy ran toward the bell and hit it with his head. They gave him the job.
The next day he went to ring the bell, tripped, bounced off the bell and fell to the sidewalk below. Two guys were walking past. One asked, "Do you know this guy?" The second guy responded, "No, but his face rings a bell."
Speaking of ringing a bell, This joke is centered around the same phrase as yesterday's joke. The humorous element is that the phrase "rings a bell" (which is usually used as an allusion to pavlov's experiments which involve dogs, bells, and salivation) is used here literally.
It it basically a pun on an entire phrase.
