Kind of surprised at the language with the Spin game: Booby prize!!! Heh. I said Booby. Heh heh heh.
Beevis & Butthead + breast joke was jarring to me as compared with the rest of the writing I've seen and my perception of the game overall.
The stuff I've seen that might otherwise appear off color tend to be a few times removed from the cliche via made up words or actions.
So instead the joke here would reference something else in the game already synonymous with stupidity/idiocy but without the breast inference. (ie Flimflam prize!!)
