Who's this guy & what did you do with Larry?

An old friend (who shall remain anonymous and also a witness protection program participant) both flattered and flabbergasted me with the following e-mail, so much so that I finally decided that it was worth sharing:
"You are ...an intelligent man, with a working mind, and a tinge of humbleness, (which) comes far and few in-between these days..... Give 'em Hell Harry at the (MCEA) union meeting and don't put your elbows on the table....."
Yep, I know.
I'm also still bemused and befuddled at this assessment.
Who is this guy, and where's Larry?
