I think they're creepy, not to mention tasteless. They're truck nutz. If a bunch of Florida lawmakers have their way, you'll be fined $60 if you get caught with them hanging from your tow hitch.
Only in America!
The sad thing is that some people thing that these are "cool." There's actually a web site where you can order these things - TruckNutz.com.
My official stand on this is that it's a shame that we should have to ban something that is assinine in the first place.
