Here's a video that'll shatter many a Hollywood movies: putting duct tape over somebody's mouth doesn't stop them from screaming, it doesn't make them stop talking and it definitely doesn't keep them quiet. In fact, putting duct tape over somebody's mouth does... absolutely nothing.
Kevin Nugent on YouTube was sick of all the movies that use this gag in tense scenes and sought to disprove it. Watch the video above because he totally did. Next time I see this in a movie, I'm going to scream out in the theater saying "HA HA. That doesn't work you fools!" (no I won't, I'll probably just snicker to myself). Anyways! Hollywood, try something different would ya? [Kevin Nugent]
