Back in the massive Jnco jeans days you could sneak almost anything in. The trick was to to put it inside of your pants and you could hold onto the larger items from your pockets. If you had an oversized hoodie on too..which we did, it gave another layer of coverage. Then have one person pay/handle the tickets and everyone else could smuggle in the goods. 2 liters, Taco bell Grande Combos, 5 lb bags of Sour Patch kids, Fast food, no problem. I did a whole pizza once, that was probably the craziest. My dad always used joke/challenge me to try and get in a bucket of KFC. I never attempted that, but it would have been hilarious to even try.
