"Hey bro, I need your help with something."
"Yeah, sure thing, what's up?"
"I'm ah, I'm going to see U2 live in concert on Sunday and I'm ... It's tough to say this ... but I'm ... not very excited about it."
"What?"
"Yeah, just, like, I'm completely nonplussed. Wait, does that mean, like, what does nonplussed mean?"
"Dazed and confused."
"Oh. Then I'm not nonplussed. I'm plussed. I'm just ... nothing. I'm unexcited."
"Detached."
"Yes, detached, just like that. I need your help."
"I can't believe this. Let's have a check-it-out. What was the first album you ever owned?"
"RTR Countdown's Hot Hits `89."
"Oh. I mean: What was the first album you ever bought?"
"The Yeshua Tree."
"What?"
"Just kidding. The Joshua Tree."
"And what was the first song that ever made you cry?"
"Running to Stand Still."
"And what was the last song that made you cry?"
"Original of the Species."
"And what's the only song that ever made you cry at a concert?"
"Bad."
"And what song did you use as the soundtrack for your first short film, and at the time thought it to be the best song ever written?"
"In God's Country."
"And what was the first song you wrote the sheet music from by ear?"
"The First Time."
"And what was the only song you could sing to Felix that would quiet him down when he was three weeks old?"
"In a Little While."
"And why did that quiet him down?"
"Because he's Oirish."
"And what's the best unrequited lovesong in the world?"
"All I want is you."
"And what's the best SONG in the world?"
"One!"
"And who's the best band in the world?!?"
"U2!"
"And what are you gonna do right now?!?"
"Go and dance to Vertigo at full volume!"
"That's right! Now show me the money!"
"Show you the money!"
"Not show you the money, show me the money!"
"Show me the money!"
"I can't hear you!"
"SHOW ME THE MONEY!"
"Do you love the black man?"
"I love black people!"
"Turn it up there, Captain."
This is a 
It's a U2 gig, you know it will rock.
I do now. I just needed reminding.
Actually nonplussed means exactly what you thought it means, it doesn't mean dazed and confused.
But it will rock. It will rock ass.
That link defines nonplussed as: "A state of perplexity, confusion, or bewilderment."
Is that not what you were feeling? Perplexed, confused and bewildered as to why you were so unexcited about seeing the Best Band In The World this weekend?
No, I just...wasn't that excited. I am now, though. Go Vertigo!
Hmm I've got R.E.M. this weekend, nonplussed by their recent album but reports from Tuesday's Glasgow Green gig have me a tad more excited - plus Ambulance Ltd, Zutons and Feeder as support isn't a bad way to spend the day - as long as the bloody rain stays off!
I decided against U2 mainly due to the ticket price of £50! But they will be ACE. Have fun!
Yeah, but slightly annoyed that their last supporting act was Keane, their next supporting act will be Snow Patrol, yet Sunday I get ... Ash & Idlewild. Wait, actually, they're both pretty good. Somebody told me it was Interpol. Hmm.
Ash suck ass.
Dude, they're Irish. You're contractually obliged to like them.
