What is it about TK and water. He is so dense that he doesn't see how that could be used against him.
He no doubt meant to refer to the Irish colloquial phrase "just a splash" used when asking for another drink of whiskey, but most people are only going to think of poor Mary Jo!
Re Kennedy's dog - who apparently is his constant companion in the Capitol Building!!!!
Splash is a Portuguese Water Dog, a breed which look like poodles, but obviously on the "high-end/low-end' scale, are much higher, so his is named for his love of water.
Proving that Kennedy is too dumb to be allowed to vote, nevermind sitting on any committees.
