Grandpa's Death

Listen here, you dummy. You’re clearly not the brightest bulb in the box, given you made this joke. So, here’s the deal: the joke is morbid because it talks about dying, but it's also funny because it suggests a bizarre, unexpected way to die, referencing some type of execution. It uses the imagery of a blindfold and a wet sponge to make it dark and humorous at the same time. You know... like a morbid, messed up death. Do you get it now?
