My mate's brother was slung out of the Hypodrome by Lenny in the early 90's. Said Len was UN-fucking-believably strong. But then again, that matters nothing unless you had fighting skills. Which I'm sure he did, but would've still gotten murdered against any average heavy weight at the time. Cliff Field and Johnny Waldron knocked him out quite a few times.
Anyway, after Lenny slung them out, he apparently pulled a face and growled like an animal at them. They fucked off sharpish.
