What's the longest you've been asleep/awake?

Longest I've been awake was only recently, this May in fact. A friend of mine and I got together after having not seen each other in almost a year, we met up on Friday night after he and I got off work and pretty much hung out at his place the entire weekend catching up on old times and playing a ridiculous amount of Xbox. I woke up that Friday around 6am to go to work and didn't go back to sleep until 7 or 8am on Sunday. Even then we only slept for about 3 hours before getting back up.

Longest I've slept would have been Thanksgiving 2001, I had a nasty cold that holiday and remember being awake and around for the family dinner and what not, afterwards I started feeling worse so I took some NyQuil. I fell asleep shortly there after and didn't wake up until Saturday afternoon, at least didn't wake up in any significant way, I was told I did wake up a few times for a drink or to use the bathroom but I don't remember it.

Jam it back in, in the dark.
