comment Are $\mathbb{C} \otimes _\mathbb{R} \mathbb{C}$ and $\mathbb{C} \otimes _\mathbb{C} \mathbb{C}$ isomorphic as $\mathbb{R}$-vector spaces?
$\mathbb{C} \otimes _\mathbb{C} \mathbb{C} \simeq \mathbb{C}$

comment Congruence modulo's in a polynomial field being a field?
Do you know some ring theory? For a ring $R$ and an ideal $I$, $R/I$ is a field if and only if $I$ is a maximal ideal. So you could show that the maximal ideals in $F[x]$ are precisely those generated by irreducible polynomials.

My comment (over a year ago...) about computational power was tongue-in-cheek. =D

I was amused to find that the wikipedia page for "Trousers" does, in fact, have your wikipedia page as a disambiguation.
