“This Fibonacci joke is as bad as the last two you heard combined”

There have been several math jokes on Fibonacci numbers. “Fibonacci joke: ‘I feel like this year’s Fibonacci conference will be as big as the last two combined!’” was posted on Twitter on June 3, 2012. “Yes, but the next Fibonacci joke will probably be just as funny as the previous two combined” was posted on Twitter on May 7, 2014.

Wikipedia: Fibonacci number
In mathematics, the Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and characterized by the fact that every number after the first two is the sum of the two preceding ones:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...

Often, especially in modern usage, the sequence is extended by one more initial term:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...

The Fibonacci spiral: an approximation of the golden spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13 and 21.
By definition, the first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two.
