comment What (fun) results in graph theory should undergraduates learn?
Just as I was writing this, there was activity on another MO question that I think gives another fun result in graph theory. The result is that, if A is the adjacency matrix of G, then tr($A^3$)/6 counts the number of triangles in G. Somehow I was totally unaware of this result, but I'll bet students would find it very interesting, especially compared to the nested for loops approach to finding how many triangles there are.

comment How do you rigidify a Bousfield localization?
You might be interested to look into Bousfield lattices, in the context of the stable homotopy category. I believe they have also been studied for the derived category of a ring and for the stable module category. A nice reference is Hovey-Palmieri-Strickland's Axiomatic Stable Homotopy Theory

comment What structure of a monoidal simplicial model category is preserved by taking the opposite category?
It's also basically never cofibrantly generated, which tends to make working with it difficult
