Lessee if I can do this without a sound clip!
start with index finger on e string, 1st fret; play note (f); place pinky on 4th fret and play note (g#); lift pinky, place ring finger on 3rd fret and play note (g); place pinky on 4th fret and play note (g#); repeat 3 or moretimes, then move to b string and play same pattern; repeat down to E and back up again; rest a bit and do again until your pinky drops off!
Well, here's a sound clip afterall!
