Coffee mugs Memes

Mathematicians have a unique relationship with mugs. Normal people buy those pretentious formula-covered mugs thinking they look smart, while real math nerds just want a donut mug because... well... topology . In topology, a coffee mug and a donut are actually the same shape (homeomorphic) - they both have exactly one hole! So that donut "mug" is the ultimate inside joke. The final panel is just the mathematician sitting there smugly thinking "I'm not drinking from a mug, I'm drinking from a torus." Pure mathematical superiority in ceramic form.
