This is a pi shaped pi pan to make it easy for baking a pi pie on pi day (March 14, 3.14). You will be the envy of all the nerds! Plus it looks like it would make a good pan for all of you weirdos who like brownies with maximum edges. “What’s wrong with edg–” YOU MAKE ME SICK.

Thanks to carey, who agrees that pi day has become more about pie and less about pi, not that I’m complaining.
