Aren't off colour jokes redundant when it comes to morning glories?
Or does it not mean the same thing in the US?

What does it mean in the uk? And could youmake a joke about fireman putting out a rubbish morning glory fire? ;)

The average man wakes up with a morning glory, lets put it that way.
I'm not sure I could factor in a fire and not make every man wince too much to get the joke.

Yes, that would be "morning wood" in the States.

Aaaaaaah!
Oh well, anyone who has heard the Oasis song (album) What's the Story, Morning Glory knows a bit more about it now.

Interesting... "What's the story, morning glory? (What's the tale, nightengale?)" has been a saying for a long time in the US. Had you heard the saying in Britain before the Oasis song title?

The prison in The Simpson's is Morningwood Penitentiary.

Never heard "What's the Tale Nightingale". But it's likely they were using the US phrase with an eye to what it meant in England. Since I knew what a morning erection was I've known it as a morning glory - it's the first thing you think of when you hear the words here.

I would say that the Morningwood Penitentiary went completely over my head. But that might be dreaming... ;)

We say morning glory here too in reference to either a morning erection or excercise of said erection with the person you happen to be lying next to at the time.

Oh, and in that same vein, if you do it in the arvo, we say it's an afternoon delight, but I'd have to imagine that's fairly common everywhere right?

Also sometimes referred to as a "nooner."
