A series of on~ramps & off~ramps of a freeway that look like a 4~leafclover.
When we took a wrong turn on the freeway in Houston, it took us an hour to go thru all the cloverleaf on~ramps & off~ramps to get back to where we needed to be!
The Clorfors were a race of tight pockets and swindlers from the planet Clorfor. You Earthlings might liken them to "space jews". You might also call me racist but it's hard to be racist towards a race that doesn't exist... Like the Clorfors!
Dirty, money-grubbing Clorfors. Tried to clorf me right out of my money. Blew those bastards up is what I did!
