Random plant sprouted in one of my solo cups??

I just see two leaves poking out of the soil, not sure why, is this a real weed growing next to my weed? It doesn't look like cannabis cotyledons I don't thnk. Should I just pull it out? Never heard of this before.

I get those on occasion. I just pull them out.

seeds in your soil or in amendments

worm casting have a lot of other crap in them for me
