Rocketship to Mars

You suddenly realize that Michael is not truly human at all!

He is one of the Martians you're being sent to kill! He has infiltrated the Space Armada to carry out who knows what evil plan! The tentacles coming out of his head had made you suspicious, but his bizarre eating behavior of wiping his fingers on only one side of his napkin gives him away.

You must act quickly. There is no time to get proof or gather vital information about his intentions. Even though you have a laser pistol on your hip, you decide it would be best to stab him.

You look down at your place setting on the table.

Do you stab him with your knife?

Do you stab him with your fork?

Do you stab him with your spoon?
