I've never written a lot of either one of them. I must be following the herd on this one. Tell you what, if I ever write the I Dream of Jeannie crossover (http://beer-good-foamy.livejournal.com/208649.html?thread=3864841#t3864841) that Beer Good seems to be talking me into (without even trying!), then I'll put either Buffy and/or Tara in.
