Yep I've seen them (the life like version)and when my 12 year old daughter question a set "Hanging" from a truck in front of us (caught at the longest stoplight in history and was hoping the whole time she wouldn't see them) I danced around a truthful, sorta, kinda,close answer, she giggled while turning red then said grossss (lets hope that's still her answer for the next 12 years). I remember a few years back seeing a pair of real 2" hex nuts hanging fron a truck hitch and it did give me a good laugh. But now the detailed version is alittle to far...
