Mid 60's the monkey and the dog were two popular dances. The song that started the dog craze actually had lyrics "Do the dog, do the dirty dog". I was in college at the time and remember a couple of bar contests to see which couple could do the dog the dirtiest. Nothing new under the sun folks.
'Course that was a college town bar, not a high school dance. Parents and teachers need to set and enforce rules. The kids will sneak out back and ignore them just like we did, but at least they know there are rules.
