Self-recursion

Just recently stumbled upon this brief page on "self-recursion" over at Wolfram MathWorld:

http://mathworld.wolfram.com/Self-Recursion.html

One example of a self-recursive statement therefrom to whet your interest:

"This sentence contains ten words, eighteen syllables, and sixty-four letters."


...and, on a more humorous note:


"What is the volume of a pizza of thickness 'a' and radius 'z'?" Answer: pi z z a.

Another nice example where one thing as well as its opposite are true:

"This sentence contains five words"
"This sentence doesn't contain five words"

Both true!
