Seasonal formulaic pun

From here:

$$\ln \left( \frac{e^{a_r} + p^2 H_a}{N} \right) = w – \ln (y) \\
%
\ln (y) + \ln \left( \frac{e^{a_r} + p^2 H_a}{N} \right) = w \\
%
\ln \left( \frac{e^{a_r} + p^2 H_a}{N} y \right) = w\\
%
\frac{e^{a_r} + p^2 H_a}{N} y = e^w\\
%
\left( H_a p^2 + e^{a_r} \right) y = N e^w\\
%
H_a ppy = N e^w – ye^{a_r}$$

Or in case MathJax doesn't work in your browser:
