“How many guacs are in a bowl of guacamole?”/“Avocado’s number.”

“Avogadro’s number” sounds like “avocado’s number,” prompting the math joke:
   
Q: How many guacs are in a bowl of guacamole?
A: Avocado’s number.
   
The pun was cite in the newsgroup net.jokes in 1985. “How many guacs are there in a mole?” was cited in 2003.
       
“What do you call 6.02 * 10^23 butts?”/“Molasses” is a related joke. Jokes on “Avogadro toast” (Avogadro constant + avocado toast) include “Avocado Toast + Mole Sauce = Avogadro Toast” and “What do millennial chemists eat for breakfast?”/“Avogadro toast.”
     
     
Wikipedia: Amedeo Avogadro
Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto, Count of Quaregna and Cerreto (9 August 1776, Turin, Piedmont-Sardinia – 9 July 1856), was an Italian scientist, most noted for his contribution to molecular theory now known as Avogadro’s law, which says equal volumes of gases under the same conditions of temperature and pressure will contain equal numbers of molecules. In tribute to him, the number of elementary entities (atoms, molecules, ions or other particles) in 1 mole of a substance, 6.02214179(30)×1023, is known as the Avogadro constant, one of the seven SI base units and represented by NA.
 
Wikipedia: Avogadro constant
In chemistry and physics, the Avogadro constant is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. Thus, it is the proportionality factor that relates the molar mass of a compound to the mass of a sample. Avogadro’s constant, often designated with the symbol NA or L, has the value 6.022140857(74)×1023 mol−1 in the International System of Units (SI).
 
Previous definitions of chemical quantity involved Avogadro’s number, a historical term closely related to the Avogadro constant, but defined differently: Avogadro’s number was initially defined by Jean Baptiste Perrin as the number of atoms in one gram-molecule of atomic hydrogen, meaning one gram of hydrogen. This number is also known as Loschmidt constant in German literature. The constant was later redefined as the number of atoms in 12 grams of the isotope carbon-12 (12C), and still later generalized to relate amounts of a substance to their molecular weight.

This Guacamole’s Got Your Number
Trader José’s Avocado’s Number Guacamole has a mind-bogglingly large number of avocados – at least five in every 16 ounce package. Lorenzo Avogadro, the math & physics whiz, came up with a mind-bogglingly large number, too (6.02214199 x 1023 if you’re curious). Make sense now? Okay, humor us; it’s perfectly logical. Because the number 5 is definitely similar to the number of protons in a gram of pure proteins, right?
