Another "guy goes to a monastery" joke - an oldie but a goodie

This is an old one, so apologies if its been here before (I haven't seen it yet, but I don't check /r/jokes every day). I'm a bit bored at the moment, so I've embellished it a bit! enjoy :)

So, this guy is hiking in the Himalayas, as you do, and, as he's hiking up the narrow, rock-strewn paths, he realises that it is getting late, and darkness comes early in the mountains, and he was still some distance from the next town. He starts walking more quickly, but it became dark and he couldn't see much in front of him. Just as the panic was setting in, he rounded a corner and lo, there was a light in the darkness. A monastery, not on any map, appearing, just as it was sorely needed.
The guy thankfully stumbles up to the great door and bangs on it loudly. After a short time, it slowly creaked open to reveal a large, almost jolly, monk with a huge smile on his face. "Come in, weary traveller", he says. Wondering how the happy monk knew English, but not wanting to look a gift horse in the mouth, the traveller thankfully entered the monastery.
"Please join us for dinner," the monk said, with that warming and happy smile. "it will be, as always, a very joyous and happy occasion".
"Thank you so much" says the traveller, as he is shown to a room to refresh himself before the meal.

At the meal, held in the large Hall, with all of the monastery's inhabitants together, the traveller is seated as a guest of honour, next to the Abbot himself. Small talk ensues as they partake of the feast set before them.
All of the monks seem very happy and friendly. Our weary traveller is confused (thinking monasteries were supposed to be quiet, dull affairs), but again, doesn't want to ask any awkward questions, and so is happy to go along.
All of a sudden, one of the monks at a lower table stands up and says loudly, "24!". The other monks start chuckling, and nodding their heads in agreement. One or two even bang their cups on the table.
Another monk then stands up and says, "37". A bit more obvious a reaction this time - the monks chuckle more loudly, a few laughing out loud and more cup-on-table banging. Even the Abbot chuckles to himself.
A third monk, "65!". Loud laughter, patting on backs, more cup on table bangings, even a few feet stompings - clearly the monks are having a good time!
The traveller, however, is as confused as all hell! Just as he was about to ask the Abbot what was going on, the Abbot himself stood up and shouted "17!". More laughter, more appreciation, clapping and table banging. The monks were loving it!
The Abbot sat down, and saw the confused look on the traveller's face. "My son", he said. "We love a good laugh, here at the monastery. We tell jokes at dinner time, and we all enjoy each others' company. In fact, we tell the jokes so often, that we ended up just numbering them - it makes it so much easier to just say the number of the joke. Why don't you try it?"

The traveller thinks for a bit and then stands up and shouts out "45". More laughter, more feet stomping, nods of appreciation, comments of 'our guest is joining our traditions" and that sort of thing.
The traveller is quite pleased with the response, and thinks to himself, "I'll have another go!"
So he stands up and shouts out "112!!".
There was a moment of shocked silence, and then a deafening roar as every monk there laughed loudly, banging on the tables, stomping their feet, patting each other on the back, pointing to our traveller in obvious appreciation. Some even wiped tears of laughter from their eyes.
The traveller sat down again next to the Abbot, feeling quite proud of himself and turned to the Abbot saying, "They liked that one, did they?"
"Oh yes," said the Abbot, "That was a good one - they haven't heard that one before!"
