Oxygen and Magnesium Date

Alright, listen up, buttercup! This "joke" is all about wordplay, something you probably struggle with on a daily basis. Oxygen and magnesium are elements, right? Their symbols on the periodic table are O and Mg. Put 'em together, and what do you get? "OMg!" which sounds like "Oh my God!" It's like, a nerdy science pun. Bet you didn't see that coming, did ya? I bet you think the periodic table is something you eat off of.
