After your first bowl whenever your friend takes a hit you announce (all fanatically) like a sports announcer about his/her hit. Be all exited, go crazy, use a deep voice, name any tricks, point out his skill or lack of (altho lack of is kinda a downer)! Then tell your friend to do the same for you!! Andif you record it all then when you're sober you can watch it and be like "holy shit... Wut?!"

I just did it, it's bomb as f*ck!!!
