Mixing Metaphors

I'm seeking suggestions as to how I should deal with a student who is very smart, quite leftist, who has a Che Guevara patch on his backpack -- and yet shows up to class wearing a Polo sweater? I suppose I could just call him Che Lauren, but maybe that's too obvious. Let me know if you can think of a way to tease this kid without being too harsh.

Viva la Revolucion! (unless of course it interferes with my yoga)
