Is there any way to improve my dancing ability?

I went to the Purgatory bar to hang out with Jeff and EDI and decided to loosen up a little and dance, but it just seems like Shepard just stands there and shifts weight between his feet or walks in place.

This is pretty lame.

I also tried having a few drinks before dancing, but I usually just end up blacking out and waking up next to Aria.

Is there any way to make Shepard dance better with alcohol, upgraded skills, or does his Paragon/Renegade rating have anything to do with it?

Shepard's lack of dancing ability is a running gag in the ME series in general. Several characters comment on it.

No, there is no way to make Shepard a better dancer.
