My wife told me a joke

Out of the blue while surfing the ‘net the other night my wife says to me:

Wife: Someone on facebook thinks you look like an owl.

Me: Why do they think that?

Wife: I dunno they just said it.

Me: Certainly something must have prompted it, what’s the context?

Wife: Grrr. No one said that. It’s a joke. I say someone says you look like an owl, you say “who”.

Me: …

Wife: Owls say “Who”.

Me: I got it. Does it mean I’m weird if I did’t care who said it – I just wanted to know how I could work on becoming less “owly”.

Sometimes, my wife must think she is married to Sheldon Cooper from Big Bang Theory.
