Are You In Love?

A young man said to his father at breakfast one morning, “Dad, I’m going to get married.” “How do you know you’re ready to get married?” asked the father. “Are you in love?” “I sure am,” said the son. “How do you know you’re in love?” asked the father. “Last night as I was kissing my girlfriend good-night, her dog bit me and I didn’t feel the pain until I got home.”
