Dude theres no way i can work out today ive been in a meat coma for over an hour.
Once my boss just went to a bbq place and eat like 2 racks of ribs, a huge side of mac & cheese, huge side of mashed potatoes, lots of chicken, like 4 pepsis, and a ton of other stuff. On the car ride home he woke up out of a meat coma, and said," zzz, oh, ice cream, ice cream, oh sorry guys i was just in a meat coma, zzz,zzz,zzzz." in a half a sleep voice. Then is wife said,"where?" he replied," zzz, chick-fil-a. chick-fil-aaa." in a half a sleep voice. So we went through the chick-fil-a drive through and got three XL soft serves, even though I said I only wanted a small.
