Happy Birthday Musical Mice - played on the piano
"Happy Birthday" played by eight very talented and musical mice! ...well, seven talented mice and one not quite so musical mouse!
One drink then pissed ? Maybe he's too thin to soak the booze up ? ( positive mental attitude !! = I'm positive, he saves a fortune as one drink is enough, so no rounds of drinks to pay for, that leaves the money safely in his wallet at the end of his short night out ) 👍
