With two pilots you should Identify, Confirm and then Select when operating any critical control.
ie. point at the switch/lever you want to move, get the other pilot to agree it is the correct one and then (and only then) select/move the switch/control.

"Hey Fred, I'm thinking of pulling this lever here, is that ok with you?" "Hmm,...I don't know about that one Tom, pulling it now may not work out the best for us at this time." "Gee, you're right Fred, my bad, how about this lever instead?". "Yes Tom, that one should be ok to pull."
Sure, this conversation may have saved that poor Robby from becoming "Heinz bean cans", but I just don't think I could do it every time I want to push a button, or pull a lever,...at least not without bursting into laughter!
