You probably couldn't see for the lights but Lyrics

One look sends it coursing through the veins, oh how the feeling races
Back up to their brains to form expressions on their stupid faces
They don't want to say hello, but I can't want to say hello
My heartbeat's at its peak, when you're coming up to speak

Well I'm so tense and never tenser
Well I'll go a bit Frank Spencer
And I'm talking gibberish
Tip of the tongue but I can't deliver it...
Properly
Oh, it's all getting on top of me
And if it weren't this dark
You'd see how red my face has gone, yeah

Everybody's trying to crack the jokes and that to make you smileArctic Monkeys - You probably couldn't see for the lights but - http://motolyrics.com/arctic-monkeys/you-probably-couldnt-see-for-the-lights-but-lyrics.html
Those that claim that they're not showing off are drowning in denial
But they're not half as bad as me, say anything and I'll agree
Cause when it comes to acting up, I'm sure I could write a book

And now that you're more than a part in the play
It's slightly easier to think what to say
You had us all standing on our heads
Doing our best tricks, yeah

Never again
Never again
Will there be another one quite as desirable as you?
One look sends it coursing through the veins, oh how the feeling races
Back up to their brains to form expressions on their stupid faces
