Few would say that President Obama's State of the Union address was funny. But he did, at one point, try to make a joke:
We've already announced over 500 reforms, and just a fraction of them will save business and citizens more than $10 billion over the next five years. We got rid of one rule from 40 years ago that could have forced some dairy farmers to spend $10,000 a year proving that they could contain a spill -- because milk was somehow classified as an oil. With a rule like that, I guess it was worth crying over spilled milk.
The joke wasn't really a hit. The audience let out a very audible groan, and Rep. Jason Chaffetz (R-Utah) was caught on the C-SPAN camera doing the rimshot gesture.
