I tried to find that list of fake funny assembly instructions last night and couldn't for the life of me. This reminded me of it. If anyone else loves funny assembly things, please save me.

yes, thank you. Looks like it was taken down which would explain why I couldn't google for it. I was looking for the COMF instruction.
