Rogue Shirt

I was getting ready for the bars on Saturday night and riffling through my dresser. I found a black shirt (my size) with the tags still on, but I swear I didn't buy this shirt! It somehow ended up in my dresser. How does something like this happen? I have three theories.

(1 of 3): The salesperson at Banana accidentally included it in my bag with my original purchase, which must have been almost a year ago.

(2 of 3): Jesus loves me. Nothing says love like a new, free shirt from Banana.

(3 of 3): I bought it because it was on sale and then completely forgot about it. Highly unlikely.
