Ephman's not really that into dance.  Unless of course it's part of a musical.  Oh actually there was this one time that his wife made him go to once before.  Get this it was a modern dance thing that was an interpretation of a famous wacked out painting.

Burn The Floor is this Viennese Waltz, Jive, Paso Doble, Tango, Samba, Mambo, Quickstep and Swing thing.  But it's no Riverdance.  There's more "sex" to it.  Ephman doesn't know about this one.  He's still going to go though.  His father-in-law was asked to be an investor.  But declined.  Probably a good move on his end. 

Maybe there is a part of him that wants to go.  It is getting REALLY good reviews.  So since as you know he'll see anything basically if it's on Broadway, he'll go.
