LOL. Yeah. I certainly enjoy living on that edge -- I like to measure the success of a joke by the length of time before someone laughs, assuming they eventually do :)

But I have to admit I also use irony in situations like this as a defense; if I come up with a wacky idea, I'll phrase it as a "modest proposal" in order to raise it, but not feel the need to justify it. Which is useful, if it invites some objective consideration of the problem and potential solution, but is also questionable, in that it would be more honest to simply say "I had this idea, is there any merit, or is it _just_ silly?" :)
