Hit It

One of me Pops favorite jokes involved hammers. 

When something had to be hammered into or out of place but required two people, he would employ it. He'd take the part in question and proceed to line it up with where it had to be driven. His exact instructions were, "Let me line this up, and then when I nod my head, hit it."

Dad meant hit the object, not his head. Just so you understand the joke.
