Also when I was in junior high and high school, we almost always had math club meetings on Thursdays, and I liked math club a lot, so Thursdays make me happy in mathy association. And then in college I rarely had labs on Thursdays, so they were often a good time to do theory homework, which means more math. Yay Thursday! Yay math!
(I miss math.)
If this is not enough, you can organize a trip to the Falls in the lobby. I love the Falls. No reason you can't get together a trip to see them, if you can find something that qualifies as a lobby in this metaphor.
