Jerry: "Well, Dave, it looks light this bowl is beat like Rodney King, but why don't you hit that and see if we can squeeze two more tokes from it."
(passes almost cashed bowl to Dave)
Dave: "Man, actually, I got a good hit from it. Kim, why don't you take a hit"
(passes bowl to Kim)
Kim: "I don't know where this is coming from! If we get a few more tokes, it looks like we might just have a Hanukkah bowl (or joint, bong, etc.) on our hands here!"
