Two dads walk into a bar. Sitting at the first table is a rabbi, a priest, and an imam. At the second there's an Irishman, an Englishman, and a Scotsman. At the third table there's a blonde, a brunette, and a readhead. Up at the bar sits a dog with a bandaged paw. One dad looks at the other dad and says, 'What is this; some kind of joke?'
