Heh, if only.
It's not so much a nervous thing as a too many thoughts at once, with too many words to describe said thoughts, thing.
Basically, if the subject is a penny laid on a train track, my first thought is the first train and all of the words to describe that thought are the cars of that train. There's thirty trains heading down the same track, back to back, at speed...
Adding alcohol just makes the impending train wreck hilarious so, yeah, highly recommended.
