Down a beer everytime Rex drops an F-Bomb, and a shot everytime someone says "Revis". I'm in for next week.
He said fuck over 30 times last night, and Revis was mentioned probably 10-15. That's about 45 drinks in an hour. Have fun.
I would say take a drink of beer for both of the situations that the OP listed and then take a shot whenever you see rex eat a snack.
As many as he dropped last night you shpould change them to shots. More dangerous, but I do not think you could buy that much beer for a one hour show.
