Husband: Love, where’s the packing tape?
Wife: (looking with a “you-have-to-ask-that-obvious-question?” face) Where do you think would be the obvious place for it?
Husband: (after reflection) Right here, in this box where we have all the packing supplies.
Wife: No, that’s where we kept it when we were packing. Now we’re unpacking. The obvious place is now different.
Huh?
