Definitely motor parts. This friggin' waiting is killing me.............and we haven't even started yet. 
All and profound apologies to Carly Simon for the harm I am about to commit here.
So, the waiting is killing you? That's got to be tough. Kind of makes one think of... oh, I don't know:
We can never know about the days to come
But we think about them anyway
And I wonder if I'll really build it now
Or just chasing after some finer day
Anticipation, Anticipation
Is making me nuts
Is keeping me waiting
And I tell you how easy it is want it done
And how it'll feel between my legs
But I rehearsed those words just late last night
When I was thinking about how right that bitch will run
Anticipation, Anticipation
Is making me nuts
Is keeping me waiting
And tomorrow we might not be together
I'm no prophet but I guess it'll take a month
I'll probably go random trajetory ballistic
Wife better stay in the mood
'Cause these are the waiting days
