i
in-n-out fries give them all to me haters gonna hate etc etc.
protip for y'all though: the combo prices are just the sum of the constituent items, so don't feel obligated to get fries or a soda or a soda instead of a shake -- order what makes you happy.
edit: also when i was like 16 i attempted to eat two double-doubles and then go to a martial arts class. that, uh, didn't work. don't think i've attempted the double double-double since.
