Trick question! Jitterbug is a general term for any kind of swing dance, so essentially, anyone who knows Lindy Hop also knows Jitterbug. Evidence: This soundie from 1944 called "Groovie Movie" calls the dancing being done "Jitterbug" but everything they are doing is Lindy Hop! http://www.youtube.com/watch?v=cbaNYWkQYYA I bet if you take that to your teacher, they'd give you extra credit! (BTW, if they say that Jitterbug is it's own dance, they are probably confusing it with East Coast Swing. Again, Jitterbug is a general term for ANY swing dance.)
