The whole night is a sham. This is what happened before the clip -
Niles saw a picture in the paper of his ex-wife Maris with another man. He is annoyed at first then his Dad Martin tells him that he should get out a bit more too. So he asks a very rich heiress to the Snow Ball. He then panics when he realises that he can't dance, but Daphne then offers to teach Niles everything he needs to know. Just as soon as Niles is getting into the swing of things his date cancels, but he doesn't want to tell Daphne as he is secretly in love with her and is enjoying dancing with her so much. His Dad knows what is going on and makes Niles tell Daphne his date has cancelled, but then when Daphne suggests she go with Niles to the Ball instead, Niles just can't say no. On the night of the ball Niles is on the point of cancelling using the excuse that Daphne probably doesn't have a suitable dress to wear, so when she appears go to the ball in that stunning red dress it is such a WOW moment! Niles doesn't want anyone to know that Daphne is just his Dad's physical therapist, so she pretends she really is his date for the night getting lots of admiring looks and when the Tango music starts - that's where the clip fits in.
After the dance Niles who has just declared his real undying love for Daphne thinks it was real for her too - until she starts talking about how they had everybody fooled. Poor Niles has to pretend he enjoyed fooling everyone too. A couple of attractive women give him their cards asking him to call them, so the night wasn't a total loss but Niles' unrequited love for Daphne continues.

One of the best episodes ever!
