What a heist dude. Can you imagine opening up and either eating or stashing an entire pack of cookies without takin' the tray, all while walking around in the store? Even more hilarious is imagining someone going to the trouble of buying them, eating them, and replacing them with oranges which they already presumably had, all to go to the effort of returning them (and hoping the counter jockey wouldn't notice "oh the seal is broken on the cookies already" and refuse the return of SIX ORANGES).
If they did it all in the store and stuck it back on the shelf, even more hilarious is that the best "substitute" they could find for the cookies was oranges. They obviously thought carefully about what would be the best fit. I KNOW, LETS JUST TAKE SOME ORANGES
Completely bizarre, what does a pack of cookies cost like two dollars?
