Nan memes

A kid gets home from school and finds his mom and dad having sex. The kid asks, "What are you doing, Dad?" The dad replies, "Having sex with your mom, son," and he starts laughing.

The next day, Dad gets home from work and finds his son having sex with his nan. The dad shouts, "What the hell are you doing, son?" The kid replies, "It's not funny when it's your mom, is it?"

I was making sandcastles with my Nan, then my mum came in the room and took away the urn.

How many people can you fit in a car?

6 - 3 in the back, 2 in the front, and my nan in the ashtray.
