See if they have free beer. Your singing sounds distorted. The beer is too weak. Have more beer until your voice improves. Don't remember the words to the song.
Beer is just right.
Play air guitar. Bed unusually hard, and full of trash and cold water. You slept in the gutter again. Treat yourself to a sleep-in until the bars open again. A herd of buffalos can only move as fast as the slowest buffalo.
