'They told me at the blood bank this might happen.'

'This is just a 15 minute power-nap like they raved about in the last time management course you sent me to.'

'Whew! Guess I left the top off the liquid paper.'

'I wasn't sleeping! I was meditating on the mission statement and envisioning a new paradigm!'

'I was doing a highly specific Yoga exercise to relieve work-related stress. Are you discriminatory towards people who practice Yoga?'

'Darn! Why did you interrupt me? I had almost figured out a solution to our biggest problem.'

'Boy, that cold medicine I took last night just won't wear off!'

'Ah, the unique and unpredictable circadian rhythms of the workaholic!'

'Wasn't sleeping. Was trying to pick up my contact lens without my hands!'

And the best thing to say if you get caught sleeping at your desk:

'Amen'
