Slam! Slam! I Shut His Lid!
I slammed the lid of a laptop shut on an engineer in my class one time because after the third time of asking him to turn off the typing sound effects in his IM program, he still hadn’t done it.
Especially annoying as we were recording the entire class. For twenty minutes you hear nothing but “taka taka taka beep taka taka taka beep bing taka taka taka bing!.”
