the prt wen sheldon tried to get make friends with the little girl was the funniest

In this episode, Sheldon says "I feel like an inverse tangent function approaching an asymptote!"; this does not make sense since inverse tangent functions do not have asymptotes (there are no values for x such that tan(infinity)=x); reciprocal tangent functions have asymptotes (for y=1/tan(x), when x=0, y is undefined).
