The most versatile fly?

[rainbowchaser]

I tied up a couple of Madsen's skunks( http://www.michigandryflies.net/file...attredirects=0 ) today. This fly can be fished dry, swung as wet fly and then retrieved as a streamer. The only other fly I would fish this way is a muddler minnow. It's also reputed to make pretty good bobber. I was wondering if anyone else has a similarly versatile fly.
