Plenty of "oo-ar", while chewing a stalk of hay (stalk, not stack); associated with intellectual challenge, broad ignorance and depthless cunning, and usually used as comic relief.
Done plenty of times on Saved by the Bell, but possibly the most memorable case was towards the end of "Jessie's Song" when the gang (sans Slater) were doing one and Lisa refused get in the stack if her hand was touching Screech's!
Also happens disturbingly often in Revolution rounds, or when the assistants launch a "Greytide." Plenty of the 'best' weapons on the station are relatively common tools that can be made in the hundreds from a stack of sheet metal.
