On Monday, you flip a coin all day. You start flipping it until you see the pattern Head, Tail, Head. You record the number of flips required to reach this pattern, and start flipping again (and counting up from 1 again) until you see that pattern again, you record the second number, and start again. At the end of the day you average all of the numbers you’ve recorded.
On Tuesday you do the EXACT same thing except you flip until you see the pattern Head, Tail, Tail. Will Monday’s number be higher than Tuesday’s, equal to Tuesday’s, or lower than Tuesday’s? No Googling for the answer! |

Yeah, I suppose so. I guess I found the comic humorous because in high school we had an english teacher that did the same thing to us, and everyone got "hungry" and "angry." No one assumed that "Gry" was the third word.

"Gry" is an obsolete word, though. Wikipedia has an article on this riddle, of course; I think the comic is referring to #1 in this list. |
