When I make a joke, it doesn't harm anyone; you can take it or leave it. But when Congress makes a joke, it's a law.
Will Rogers (attrib)
...and in the same vein:-
Be thankful we're not getting all the government we're paying for.
There's no trick to being a humorist when you have the whole government working for you.
This country has come to feel the same when Congress is in session as when the baby gets hold of a hammer.
