Yes there have been but be very wary of making false equivalencies. The left does that all the time - every day. It becomes such a pattern that people don't even recognize it after awhile.
Leno's joke is borderline but Letterman's was clearly way-way-way over the line on many levels then he lied about it. That's what contributes to making the parallel between the two jokes false, IMO.

Good point. On some blogs, the leftists are deflecting this into a discussion of Obama’s health care plan, and our people always take the bait. Next thing you know there are a hundred technical posts and the left has won with another intentional deflection. We have to stay on topic and hammer them.
