More Cowbell Shirt - Classic Will Ferrell SNL More Cowbell shirt. Bruce Dickinson would be proud. Come on baby, don't fear the Cowbell or Blue Oyster Cult. We'll even throw in some bitchin' More Cowbell shirt stickers of the same design! This More Cowbell shirt is the only prescription for your fever, baby. (via VintageCotton.com)
