Joerg, "Lysol" is a brand of disinfectant liquid cleanser, typically used to clean kitchens, toilets, etc. Spaw is talking about "cleaning" the "dirty" comments (sexual innuendo--"G spot", "I'm on top") in Rick's and Margo's posts.

Actually, I don't think he really wants to clean them up, he's just shocked by the competition in making dirty cracks--farting around, so to speak. (Oh, I slay me! Dirty cracks--farting around! Really, though, that stinks. Oh--another one! Stop me before I kill myself. What do you all mean, I won't have to do it myself?)
