Unless you count Clitandre's "vast German breeches" (2.1.40), there isn't much steaminess up in here. No sex. No kissing. No hugging. Not even a date, unless being in your girlfriend's room with four other guys counts as a date. We're only giving it a PG rating because there are a few curse words and we're not sure toddlers should be watching dramas about rampant infidelity.
Then again, those SpongeBob episodes can be pretty risqué.
