An Alzheimer's Purchase is when you buy something online that takes so long to be delivered, you forgot you ordered it in the first place.
Girl: You like my necklace?
Boy: That's very nice! Where did it come from?
Girl: I bought it online, but it took so long to get here, I forgot about it.
Boy: Nice Alzheimer's Purchase!
