>> Why is it funny that he stood up and said he had a beard, since everyone can see he has a beard.
Would it be funny if his name was Baird? What if instead of offering everybody a beer, he offered them a beard?
Alternatively: previously you described how sometimes you act obtuse to see how long you can string it on. Are you doing that to poor BF? ;-)
More importantly, why is it funnier than somebody who has a beard, admitting it? Next you'll be asking questions about the game of Cricket.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
