LOL!!
Oh yeah, I've been that tired but haven't quite gotten to the falling asleep stage. I have found both hubby & our youngest in just that position though - and I'm never quite sure if I should wake them (and embarrass them) or just leave them alone.
With the little one, I'll usually just pick him up & take him to bed. But, I've been mean & sneaked back out of that particular bathroom and left hubby there (hey, we have 3 full baths - he didn't need to know that I found him that way

)
