You might be thinking of the time I searched my diary archives for sentences in iambic pentameter and managed to find just enough rhyming ones to turn into a rather disjointed not-quite-sonnet, but that certainly wasn't my collection of filk-seeds.

My filk-seed collection includes, off the top of my head:

In short, in matters vegetable, mineral and animal
He is the very model of a modern David damerell

I'm the dandy webmaster who you're too scared to mention
I spend my cash on writing Flash and grabbing your attention

Quick reflexes are a must for the habitual player of what is known as (Half-Life)

He works with a mouse, a very big mouse, he's a compsci

drswirly

Generally, though, my attitude to filk is that once you've come up with the one outstandingly well crafted line that sparks the whole thing off, coming up with enough filler to pad out the rest of the song is not really motivating and you might just as well leave it at that.
