• The darkest hours come just before the dawn. So if you're going to steal your neighbour's milk and newspaper, that's the time to do it.

• Never test the depth of the water with both feet.
• If you think nobody cares whether you're dead or alive, try missing a couple of mortgage payments.
• Before you judge someone, you should walk a mile in their shoes. That way, when you judge them, you're a mile away and you have their shoes.
• If at first you don't succeed, avoid skydiving.
• Give a man a fish and he will eat for a day. Teach him how to fish, and he will sit in a boat and drink beer all day.

• If you tell the truth, you don't have to remember anything.
• Some days we are the flies; some days we are the windscreens.

• Generally speaking, you aren't learning much if your lips are moving.
• Never miss a good chance to shut up.
• Experience is something you don't get until just after you need it.
• When we are born we are naked, wet, hungry, and we get smacked on our ####. From there on in, life gets worse.
• The most wasted day of all is one in which we have not laughed.
• Remember not to forget that which you do not need to know.
