David Ross talks about teaching Derek Lowe the suicide squeeze sign just moments before his at-bat (where he suicide squeezed):

"He was like, 'What is the sign for the squeeze?' and then when I touched in the area, he said, 'Are you sure?' Ross said. "So I turned around and asked some of the guys to confirm I was right. [Lowe] is so scatter-brained that it's hilarious.

No, hilarious is not the word I would use. One would think that when you're the team's highest paid player you could bother to at least learn the signs.
