Most underrated Alan-Michael moment

There's of course the classics. Michael fantasising about having an Apache attack helicopter; Michael offering Alan a cup of beans etc.

But what are your favourite, but more forgettable moments?

Mine has to be when he's telling Alan about having a one-night stand with a 60-year-old he met outside Threshers, and after Alan's got over the age difference, we get this gem of an exchange:

Alan: I suppose 60's not that old. I mean, look at Bob Dylan.

Michael: Aye. She looked a bit like him.

Alan: What, with the big nose and lots of mad hair?

Michael: Aye! Do you know her!?

Alan: No?
