Everything Comes In Threes
Not true. In reality, everything comes in ones. Sometimes, when three "ones" come in a row, it seems like everything comes in threes. By the way, in ancient times it was widely believed that everything came in twenty-sixes. They were wrong, too. It just took them longer to recognize the pattern.
You Can't Take It With You (When you die)
Well, that depends on what it is. If it's your favorite blue suit, you certainly can take it with you. In fact you can stick a whole bunch of other stuff in the pockets just in case you do take it with you.

Not necessarily true. Today is another day. We have no idea what tomorrow is going to be. It might turn out to be another day but we can't be sure. If it happens, I'll be the first to say so, but you know what? By then it'll be today again.
A Bird In The Hand Is Worth Two In The Bush.
