Ketchup Blindness

A rare phenomenon wherein the affected person can not find the item they are looking for in the refrigerator, despite looking directly at it several times. Affects more than one in seven married men.

Husband: Why are we always out of ketchup?
Wife: What are you talking about it's literally right in front of your face!
Husband: Oh, no... I have ketchup blindness.
Wife: Noooooooo!
