Thought for the (Mon) day

I was recently sent these, thought they may cheer up a Monday at work after a lovely sunny weekend...

• Do not argue with an idiot. He will drag you down to his level and beat you with experience.
  
• The last thing I want to do is hurt you.  But it's still on my list.
  
• Light travels faster than sound. This is why some people appear bright until you hear them speak. 
  
• If I agreed with you, we'd both be wrong.
