These are the ten best things to say if you get caught sleeping at your desk:

10. They told me at the blood bank this might happen.
9. This is just a 15 minute power-nap like they raved about in that time management course you sent me to.
8. Whew! Guess I left the top off the White-Out. You probably got here just in time!
7. I wasn't sleeping! I was meditating on the mission statement and envisioning a new paradigm.
6. I was testing my keyboard for drool resistance.
5. I was doing a highly specific Yoga exercise to relieve work-related stress. Are you discriminatory toward people who practice Yoga?
4. Darn! Why did you interrupt me? I had almost figured out a solution to our biggest problem.
3. The coffee machine is broken . . . 
2. Someone must've put decaf in the wrong pot .. . 
And the #1 best thing to say if you get caught sleeping at your desk . . ." . . . in His name. Amen.
