Papa: Johnny, Johnny.
Johnny: Yes, Papa?
Papa: Open wide.
Johnny: HAHAHA.
Papa: *unzips pants*
Johnny: *crying* No, Papa!
Papa: Johnny, Johnny.
Johnny: Yes, Papa?
Papa: Open wide.
Johnny: HAHAHA.
Papa: *unzips pants*
Johnny: *crying* No, Papa!
Alright listen up, dumbo. So, basically, the joke sets up a childhood call and answer. But then daddy wants Johnny to open wide which sounds like the setup for something NAUGHTY. The 'HAHAHA' turns into 'crying' real quick when Johnny realizes what's up. You think that's funny, you sicko? You need help.
