Today, my husband and I ACTUALLY had this discussion.
Me: "Can I have a pony."
Husband: "You can have an imaginary pony!"
Me: "That's stupid! I want a REAL pony."
Husband: "Yeah but can a REAL pony do backflips?"
Husband: "I have an imaginary pony and HE can do backflips."
Me: "My real pony could do imaginary backflips."
Husband: "My imaginary pony can do REAL backfips!"
Me: "NO WAY. An imaginary pony can only do imaginary backflips. And ANY real pony could do an imaginary backflip."
Husband: "That's ridiculous. Imaginary ponies can do REAL backflips."
Me: "That's like saying an invisible man can do a visible cartwheel."
Husband: "Just because the pony is imaginary doesn't mean his backflips are imaginary. He can still do both imaginary and real backflips."
Me: "Ok, have your pony do a "real" backflip and I will tell you if it was real or not....Don't make me call an expert witness."
Thankfully our check came at this point in the conversation.
