At Capcom's booth at San Diego Comic-Con 2011 they have a screaming contest booth that measured how loud you could belt one out. The loud screams won an Asura's Wrath hair headband. The loudest screams get the screamer entered in a drawing for tons of Capcom goodies. The ones not quite loud enough just got laughed at.
Most of the guys sucked. It was the girls that made the meters peak, as you'll see above.
