No, not Del falls though the bar and Trigger makes a face.
I bring this up because BBC Four look like they are re running Boys from the Blackstuff and so my undisputed candidate for this title is probably coming up.
It's in Yosser's Story and if you've seen it, you'll know what I'm talking about, and if you haven't, believe me, you won't appreciate a spoiler.
A brilliant moment of crushing farce coming out of the deepest, most desperate tragedy - when it first hit me, I was off the sofa, helpless with laughter, on the floor in seconds and when I finally came round found I had to rewind about ten minutes to watch it again. Apparently Tom Georgeson (who plays Dixie Dean in the series) had much the same reaction.
So, that's my candidate. In a few weeks you'll get a chance to see if you agree.
What's yours?
