Mum: *listening to radio about the dangers of giving children alcohol, occasionally laughing her head off*

Me: did you know Americans can't drink 'til they're 21?

Mum: what, seriously? That's terrible! *thinks* How old do they have to be to buy guns?

Me: uh, I dunno. Younger, I guess.

Mum: well, if they're not old enough, they could go to the shop with the gun & say 'give me a drink!'

My mum; advocate of armed robbery, but only when you really need a drink.
