Dad joke

SCENE: My teenage daughter and me in the car.

Lauren: Dad, do you know what the most commonly used letter in a girl’s name is?

Me: Hmm, is it a consonant or a vowel? (Silence.) Please tell me you know what consonants and vowels are.

Lauren: You’re no fun, Dad. Forget it.

Me: What is a vowel?

Lauren: OK, OK. A vowel is … ahh … eh … well, oh … uh …

Me: Close enough.
