Jason had challenged Sal to a Pouch-Off, in which they each make pouches out of the foreskins of their uncircumcised penises and then see who could stuff the most M&Ms inside.
After dropping his pants, Jason asked Robin to evaluate his penis--she said he had "a good-looking piece." Sal got defensive: "You heard of the story of David and Goliath, Robin?"
As Richard dropped M&Ms in his pouch, Sal began to get confident: "25, you motherf'er! Lick my balls, you Australian piece of horseshit!"
Richard then pumped even more into Jason's pouch--eventually fitting 50. Sal had topped out at 29, so Richard laughed: "He's been out-pouched."
Jason shrugged: "There's a little bit of a tingle in my knob."
