This week's Clapper shot is from one of the all-time great episodes (at least, in my opinion!), "The Trouble With Tribbles". This scene features Captain Kirk getting an update from Dr. McCoy on just what the heck these tribbles are. A plastic bin filled with the pulsating little beasties sits between them.
Clapper info: August 22, 1967 / Scene 33A / Take 2.
