Sink Memes

Trigonometry nerds unite! The meme shows a kitchen sink (sink) above "Cos K" pointing to a tank. In math, the cosine of K is written as "cos K"... and what's a sink divided by cosine K? A TANK! Because sin(k)/cos(k) = tan(k). It's basically a visual equation: sink/cos(k) = tank. The kind of joke that makes math teachers secretly giggle during faculty meetings.
