“Teach your children about taxes—eat 30% of their ice cream”

“Teach your children about taxes—eat 30% of their ice cream” is a jocular saying that has been printed on ecards and posters. The joke was first told by American television host and comedian Conan O’Brien, who tweeted om September 4, 2011:
   
“Just taught my kids about taxes by eating 38% of their ice cream.”
 
The percentage varies. “If you want to teach your children on the nature of taxes, eat 50% of their ice cream” was cited on Twitter on January 22, 2013.
 
A similar remark about candy had been posted earlier. “I’m looking forward to teaching children about taxes tonight.  I will take 40% of their candy and redistribute it (mostly to myself)” was posted on Twitter by Matt Singley on October 31, 2008.
