An amiable person will give the joke teller a courtesy laugh although he/she doesn't even deserve one.
Bob: Cause it was hungry and wanted to eat some bbq chicken!
Bob: hahahahahahahahahahahaha, lol, rofl, lmao
Mike: that's nice...
Bob: you get it? the chicken ate bbq chicken and crossed the road cause it was hungry!!! hahahahahahahahahaha
Mike: yeah, i got it.
*Bob leans into Mike and laughs
Mike: wow, you totally just busted a geng...
...Bob goes to a nearby person and tells the same joke in hope of meeting someone who laughs. However, he will most likely bust a geng again.
