Happy Pi Day

It's the end of Pi Day (or more appropriately Π Day) here in the Middle West of the USA, but this is still a fun comic from Rockwood.  It only works in month-day readings of the calendar.  And the real geeks should only celebrate around 3:49 am.  This came via my brother-in-law, who loves a math joke our cousin, who is another chemical engineer.  My wife loves, "pi are square."
