BtVS: Bad Girls / That's one word three times

SO in Bad Girls...

...Wesley arrives, Faith and Buffy do the silly hands in the air dancing, a blobby villain gets fritzed and Faith kills a human... and goes bad. Despite all that, it was a bit forgettable... not much great dialog, not a great deal to laugh at, and it's hard to care.

I thought I remembered Faith vigorously washing her hands and was going to link it in with this piece by Rose George on how we could do with being a little more diligent on that front - but when I went to grab a screencap it showed Faith vigorously washing her top.

Wesley: Remember the three key words for any Slayer: Preparation... preparation... preparation.
Buffy: That's one word three times.

One word three times:

Rules of Buffy:
I pondered making the deputy mayor's demise an example of Rule of Buffy #1 - but he wasn't really nice.

Maybe too early to say but could be a new Rule of Buffy - "If you dance with your hands above your head you're probably bad"
