Grey Elephants in Denmark - Number Trick
- Pick a number between 1 & 10.
- Multiply by 9.
- If the result is a two digit number, add the two digits together.
- Subtract 5 from the resulting number.
- Beginning with the letter A as 1, count over in the Alphabet that many letters ( I usually will count a few out loud " A is 1, B is 2, C is 3.")
- Now think of a Country that begins with your letter (Only big Baseball fans, or Cigar smokers will get the Dominican Republic, the rest will get Denmark)
- Take the second letter in your county and think of a Circus Animal that begins with that letter.
- Wait a couple of seconds and say "There are no Elephants in Denmark!"
Explanation: The result of step 3 (adding together the digits of a multiple of nine) will always yield "9", so subtracting 5 yields 4, which in turn forces the letter "D".
