IQ Is Less Than His Age

(Our Mum’s 50th birthday is coming up, and I approach my 18-year-old brother about ideas for how we can celebrate it. I’m trying to be sneaky in case mum hears.)

Me: “Hey, so I was thinking about next Friday. We could do Karaoke, or maybe go and see a play?”

Brother: “I can’t, I’m busy.”

Me: “What!”

Brother: “Well, sorry. But it’s my Mum’s birthday. I can’t!”
