When Gary Larson decided to draw a little comic about Albert Einstein (an amazing mathematician) playing basketball, I wonder which number he would pick to put on Einstein's jersey? Oh, 27.
(Notice the other numbers: The perfect cube before 27 is 8. 3^3 is 27. Notice the 10 has a hand over it, if you use the 10 twice... 12-10 and 35-10 and add those answers together... 27. This is how my mind works.)
