Hello TDU people, I know this topic may have come up before, but, it is a
very Tram Gunzel Topic. Many a web search reveals nothing. So I resort to
our faithful group to re-affirm our understanding of this term. To my best
understanding it is used to describe someone who is "Over Acting " (Just
like some of our trolley crazy friends) The Goon Show is the most possible
source but if so, which sketch? I have done a few searches and nothing can
confirm.
So Gunzels! What's a 412 please?

Now don't overwhelm me with responses please, or even over act, that is
just too 412 for comfort.

Awaiting in suspense (not overacting)
