" My gut felt like it was full of boiled towels. I did a Sailor’s Morning Prayer: I went downstairs, shook up a Stella, and chugged that foamy mess in one go. Sure enough, that little cherry bomb got my whole bag heavin’ and I blew about a gallon of hot, fried disaster into the sink (don’t worry, I used the garbage disposal side)." -Raymond Q. Smuckles
"My uncle would wake up at 12:30 every afternoon, say a Sailor's Morning Prayer in the bathroom, and begin his day of drinking."
