The first joke was nearly impossible for anyone to get that hadn't seen the picture. This type of pun is difficult to explain when you can't see the word spelled out.
Until I sent this joke to school, I was unaware that most children don't know their shoes have tongues. This was another one that warranted a lot of explanation. Big joke book is striking out this week.
There's a chance I'll have some explaining to do with today's joke as well. I'm unsure if the kiddos will know what smoke signals are.
I'm going to flip through the book until I find one that's easier for tomorrow. These kids deserve a good joke.
