Warning: logic ahead

Girl #1: You're drunk.
Girl #2: I'm wearing sweatpants, so I'm obviously NOT drunk!
Girl #1: What?! Explain.
Girl #2: I'm wearing sweatpants. I wear sweatpants when I'm alone. I don't drink when I'm alone. Therefore I can't be drunk.
Girl #1: You're wearing sweatpants now, and you're not alone....
Girl #2: I'm NOT drunk!
