Here's one:
You are going to the market and you come across a man driving his cows. There are seven cows, each have seven calves, each calf has seven horns. Counting all the cows and all the horns, how many were going to the market?

"You're a soldier now,
Fighting in, a battle,
To be free, once more,
Now that's worth fighting for!"
