"Could you please go shopping for me and buy one carton of milk and if they have avocados, get 6.

A short time later the husband comes back with 6 cartons of milk.

The wife asks him, "Why did you buy 6 cartons of milk?"

He replied, "They had avocados."

That sounds perfectly rational to me

Nice play on words

Brill, had to explain it to SWMBO though

I must be getting old, had to read it twice.

Now that's funny!

I keep telling my wife I don't know what you mean, I only know what you say.

I just posted this on my Facebook page, what do you want to bet that I'll need to sleep with one eye open tonight?

It would make no difference to me as I'd have bought the wrong milk or wrong avocados anyway.
