Hello, spoonernut, and welcome to the board.

Flutter by is a favorite, and I'm glad to learn your Iditarod spoonerism. I would also like to see your trucker one. To spare the more sensitive, may I suggest that you post the spoonerism in white type, so that only those really wishing to read it do so?

To post in white, do this:

<white>trucker => adgff</white>

with the angle brackets replaced with square brackets.

The finished product will look like this:

trucker => adgff
