Plot Bunnies

I really hate plot bunnies. I get one good idea going, and I start the story, then another idea hops into my head. AH! It's insanely annoying. Last night, yet another plot bunny started hopping around and I can't get it to leave! ARG! (For those of you who don't know, a plot bunny is a story idea that hops around in your head while you're working on something else.)

Coral: Hey! What about us?
Nicki T.: IT'S NOT MY FAULT!!!!!!!
Sir Eli: Have you ever tried telling it you'll save it for National Writing Month!
Nicki T.: I did. And guess what? IT DIDN'T WORK!
Jarek: I don't see how you can think our story is boring.
Nicki T.: It isn't. It just needs some work. I'll get to you eventually. And whatever I research for them benefits you too. And I didn't say I was going to write it first.
Coral (tiptoeing up behind Jarek): Seems that way.
(Coral yells. Jarek jumps and screams.)
Jarek: AH! How many times have I asked you not to do that?
Coral: Thirteen by my count. Did you count fourteen or something?

ACK! I hate plot bunnies!!!!!! Maybe, since something lacks in the idea I have, I'll save it for National Writing Month. That would give me time to work on it. I don't really know. Any helpful ideas would be appreciated.
