I think my favorite so far is Bet the Ranch.

Bet the Kat

B and D, or Bea and Dee (a minor third and a sexual practice. You might have to change your initial, Kat. The Germans go up to H, but I don't know of any note called K.)

Hermony (that must have been done)

Nose to the Rhinestone (that was just free association, and it might have nothing to do with any of you)

Bet's Got Your Tongue, Bet's Nine Lives, Bet in the Hat--maybe there's a version of that that isn't as lame as the above, or that works if your other sisters participate.

Our Children's Aunts. Okay, it's a little weird.
