Thanks. If I do decide to leave the airport the first time around, I'll still be skipping the Pyramids since I'll be seeing them when my friend is with me on the way back, but the more remote ones are also a possibility for then as well. What I'm after is if there's things that I obviously wouldn't do with my one day (so therefore my friend wouldn't be upset about missing) and is worth the cost, whatever it may be, to get a visa and leave the airport.
By the way, I checked out your link, and that looks absolutely amazing. I took a year off after graduating to travel, and while I kept a blog (on Travelpod) I wish I had the enterprising ideas you had to sponsor the trip. The dare idea is absolutely brilliant, and I think my friend and I will incorporate it to rack up beer debts between each other. Thanks again.

I think you could make 10 hours to the pyramids and back. Out of a 10 hour layover, you'll probably spend at least 3 of those in the airport coming and going, so you only have 7 hours from airport exit to airport entrance. It'll probably take 2 hours round trip with decent traffic to get to the pyramids, so you can have time to go see them and get food but it will be a bit rushed. I think if you have a 24 hour layover you'll be good to see a lot of things. Maybe try on the 24 hour layover to go see other Pyramids way on out like Saqqara, Memphis, and Dahshur which is an easy 6 hour day trip outside of Cairo.
That's what i'd do, at least. It would be fairly expensive for the taxi's but is pretty worth it. I think a Taxi for us from Central Cairo to Saqqara, etc was 250 pounds ($50) for most of the day. Probably more from the airport though.
