Rest-A-Rea.....Rest area.
So I pass this JB truck one day down in Texas, the driver is standing up (I see him in his West Coast mirrors as I come up on him) kinda leaning over the steering wheel of his cab-over.
I get on the radio and say "JB, are you okay"? He replies, "I'm fine driver, I just feel a little embarassed". "What's wrong"? I ask.
"Well, I've had this stomach flu and I crapped my pants".

"Don't worry JB, I won't say anything, as a matter of fact I see a rest-a-rea coming up, stop and get yourself all cleaned up". "Okay, will do" he says.
As I look in my mirrors, I see him truck right on by. "Hey!! JB, I though you were going to stop and get yourself cleaned up"? "I was", he said "but I'm not done yet"!!
