EMPLOYER: Josh Bernstein
PREREQUISITES: MM #51 (Hang Ten), Must be Trevor
REWARDS/UNLOCKS: Bouncy Bouncy
1. Pulverizer: Use a melee weapon to beat up Avery.
2. Seized: Stops Avery's car within 40 seconds.
This mission starts Trevor getting his "Bouncy Bouncy" - just as Josh had promised in the last mission. Afterward, Josh will ask Trevor to go send Lenny a "Wake-up Call".
Go ahead and take Josh's car afterward (there's a little bit of dialog here if you do) and then, if you care about one of the mission's medals, be sure that you have some sort of melee weapon on hand. If you don't, you can always go stop by an ammu-nation on your way to Lenny and buy a nightstick.
Once you get close to the objective, Trevor will call out to a nearby jogger ("Hey Facelift!") and ask her for information. She'll note that Lenny is showing the house nearby on the left. Get your SMG ready...
Enter the last driveway on the left of the street and Lenny will try to speed away in his green comet. Quickly shoot out the tires. If you can't get him on the first go, quickly drive after him and try to shoot them out again. We have to be fast for the mission's last medal requirement. If all else fails you can always come back to redo this and just ram him until he gives up.
Once he gets out of the car, be sure to use your melee weapon on him once or twice (don't go overboard - killing him fails the mission). Lenny will get the message and your job will be complete.
