As a memory exercise many years ago, I learned Pi to this many digits: 3.14159265358979323846264338327950 and, for a while, even added 288419716939937510 to get to the next zero.
 
Then, one day, at my dart bar for a league match, my favorite waitress comes in wearing a t-shirt that says:
 

 
Gee thanks. 

Beagle
pi is an irrational number, ...

Thus it's honorary mention here in this place... where it indoobila... indoobila... indubitably fits right in.
 
(an "irrational" number means it goes on and on and on and on and o.........................................)
 
Sorry, was I rambling?!
