I may have screwed up ....more than once

Hey i built a stout 4V 351 Cleveland for my 1972 Ranchero. I was just about ready to start it when my brother in law that doesn’t know much about cars, points to something on the floor and says, “doesn’t that belong in there?”
Sure enough I left the torque converter out!

I did that on a 4x4 truck once.
We were in a hurry to get that truck out before closing.
Didn’t notice until I went to put the dust cover for the converter on.
Of course everyone thought that was hilarious. LOL
I stayed after closing and finished it.
