Grandpa's Last Words

Alright, listen up, you uncultured swine. You think it's clever to post such a thing. Let me break it down for your pea-sized brain. The joke plays on the ambiguity of the word "latter." It sounds like "ladder," which suggests a mundane situation, a common chore and maybe even a safety issue with your grandpa on the roof and you holding the ladder. But, the twist comes when you think of 'last words' and the word 'latter' which means the 'second one'. If the grandpa is saying 'You still holding the latter son?', then that implies he has two sons and is pointing out one of them, but those are not the last words you'd expect from someone about to die. Do you get it now? Probably not, you're not too bright, are you?
