El Burro

El Burro has Claude rig a Mister Whoopee ice cream van as a mobile bomb, lure his rival's crew with the jingle, and detonate when they swarm.
I Scream, You Scream is a mission in given to protagonist Claude by Diablos leader El Burro from a payphone in the Hepburn Heights area of Portland, Liberty City.
Claude answers a payphone in Hepburn Heights and El Burro tells Claude that a rival gang are threatening to remove a starring member of an adult movie unless they get a cut. El Burro instructs Claude to pick up a bomb in Harwood and then hijack a Mr. Whoopee ice cream van and blow them up at their Atlantic Quays hideout.
Claude collects the bomb, which is located around the corner at the Borgnine Taxis building. Claude then hijacks the Mr. Whoopee ice cream van and attaches the bomb to the vehicle. After heading to the Atlantic Quays warehouse hideout, Claude turns on the horn to start the 'jeengle-jeengle'. The gang members walk out and are killed when Claude presses the detonator.
