```   "The 288th day of the year; 288 is the super-factorial of four.
1! * 2! * 3! * 4! = 288. It is important that math students learn
not to say this number in public as it is two gross. (I apologize
for the really bad pun)"

"288 is also the sum of the first four integers raised to their own
power:  1^1 + 2^2 + 3^3 + 4^4 = 288"
