The Flash was lit and so was Barry as the boys took the speedster out for his bachelor party. And to make sure Barry had a good time, Cisco made a super drink because normally Barry's fast metabolism burns the alcohol too fast.
Barry was hesitant to drink in case the city needed the Flash, but Cisco promised to be the "designated superhero."
Barry ended up getting really really drunk. He even told the patrons at the bar that he was the Flash.
Then he got hit with a massive case of the munchies and had to devour some peanuts and hot wings.
Things got a little heavy after Barry lamented the ending of the film Titanic. But luckily Barry was given a chance to sober in a jail cell.
