Mickey Rourke: Hey Dykstra ... I'll Rip You a New A-Hole (VIDEO)

Mickey Rourke wants to get his hands on Lenny Dysktra in the worst way ... after Lenny's rant about him on Howard Stern.

Rourke railed on Lenny Saturday as he was leaving Caffe Roma in Bev Hills. Lenny told Howard Mickey owed him $30k, and strongly insinuated it was for coke.

Mickey is clearly indignant and feels Dykstra should be grateful for saving his ass because the coke dealers were after him.

Note to Dykstra ... don't go to Caffe Roma.
