After all this years, Michael Winslow still is amazing. My brother and I tried to mimic him w/out success when we were tiny kids (I don't think it was age appropriate for us watch Police Academy but most guardians leave their kids in front of the TV. Not a good thing.)
Called "The Man of 10,000 Sound Effects" and famously known as 'Sgt. Larvelle "Motor Mouth" Jones' in the Police Academy. He also appeared in "Spaceballs," a spoof on George Lucas' "Star Wars".
