"Happy Fun Ball" is one of my favorite Saturday Night Live commercial parodies. After doing some reading of actual drug warning labels, I realized this sketch wasn't much of a stretch.

• "Gas with oily spotting, loose stools, and more frequent stools that may be hard to control."

• "[In a small number of people] your skin and the whites of your eyes turn yellow."

• "Serious risks include decreased sweating."

I posted this quiz over at mental_floss: The Not-So-Fine Print: Popular Drugs, Ominous Labels. Match the drug to the safety information on its warning label. Are you taking the drug that might cause hard-to-control defecation? Better test your knowledge of possible side effects.
