I have occasionally noticed a hidden triple in a house with only 4 unsolved cells. Only in that way did I notice the resulting naked single. Thump -- I could have had a V-8. Duh!
They're ba-a-a-a-ack. I saw a "could've had a V-8" commercial just this morning.
A young mother was trying to get her infant son to eat a french fry. The kid thumped the mother on the forehead with the heel of his hand, as the announcer intoned, "Could have had a V-8".
