A man called his boss one morning and said, "I can't make it to work today. I am sick."

The boss asked, "What's wrong?"

The employee replied, "I have anal glaucoma."

The boss said, "What the hell is that?"

The man replied, "Well, I just can't see my ass coming in to work."

I laughed out loud at this one.  Great joke!!  I am going to use this one at work tomorrow.
