At this year's Bonnaroo, they've been hosting a series of all-star SuperJam sessions. But none of those can hold a candle to Animal Collective's late night jam with a very special guest: Michael Winslow, otherwise known as the sound effects dude from the Police Academy movies.

Here's what they said on Instagram: "Michael Winslow jammed on stage with us at Bonnaroo last night. We got the bleeps, the sweeps and the creeps." Amazing. Update: Check out a video snippet below, plus a photo by Mitch Manzella.

Below, watch Michael Winslow in the first Police Academy. Then, watch Animal Collective perform "Today's Supernatural" at Pitchfork Music Festival 2011.
