Back of Big Rig Trailer
A big rig passed me on the interstate, with this on the back of his trailer:
S. L. O. W.
'Supersonic Lowflying Outlaw Wagon'
And judging from the way he passed me (had to find out what S. L. O. W. meant), took me a while to catch up to read the small print, he was RIGHT!!!!!
The driver could be seen in his mirror laughing as I caught up w/ him.
