Is there any other kind of julep?

There's Orange Julep: http://www.orangejulep.com/html_e/index.htm
Hawaiian Julep: http://www.hawaiianjulep.com/
Champagne Julep (pmf): http://www.atontour.com/cocktail/388/Champagne+julep.html

Yes, but Hawaiian Julep is a Texas-based company, not a drink; Orange Julep is a latter-day soft drink (not to be confused with Orange Julius); and Champagne Julep is just a minty variation with Champagne instead of Bourbon.

Not to be picky or anything.
