Dude, I can't help asking. I tried not to, but I can't help myself..... What in the world???

Guess you've gotta be "in the know"... I got the fact that Granpa stuck a big one, but I'm left wondering if he also shot a guy named Bob, shot an actual cat named Bob, or ifGranpa AND Bob went out and stuck a big one. Oh yeah, and what's the "recipe", and what's it a recipe for???
