My gf and her best friend and I were at a cafe in high school. Best friend's bf was packing serious heat, and everyone knew it, kind of a school joke.
Gf: "OK. Seriously. How big is it?"
Her friend slaps a full can of AquaNet Extra Super Hold (in the pink can) on the table. (It was the 80s! Not like we had a banana for scale.)
"I... I'm not sure, not sure... I believe that... um..."
Gf: "How?!"
Best friend: "No idea, but it fits."
