This problem has been driving me insane for years so thank you, I, Anonymous, for being here for me. I was talking with my friend about how "Lars Larson gave me herpes". It's not true but really funny to say it out loud. He said it's against the law to say things like "Lars Larson gave me herpes", if it's not true. He said, "Only someone that got herpes from Lars Larson can say, 'Lars Larson gave me herpes.'" So I guess if this gets censored, I will understand, and concede to my friends legal advice.

[The question is, if you say "Lars Larson gave you herpes," would the average person believe it? If the answer is yes, then it's actionable. However, Lars Larson is a public figure which (perhaps unfairly) gives him less right to complain if people are making jokes about him. Anyway, back to our original point: If the average person did NOT believe it (in part because you followed it up with "it's not true" and you meant it in a funny way), then that's known as "parody," and makes it tough to prove in court that your words were personally damaging to Lars and/or his livelihood. Therefore one could say, "Lars Larson gave the world herpes," and that's probably okay, as well as "Lars Larson gave Lars Larson herpes," and, "Lars Larson gave herpes herpes."—I, Anonymous Legal Team.]
