A few oldies but goodies for you Jill:

Why don't scientists trust atoms? Because they make up everything!

Why don't seagulls fly by the bay? Because then they would be called bagels!

Why did the tomato turn red? Because it saw the salad dressing!

Why did the chicken cross the playground? To get to the other slide!

Why did the math book look sad? Because it had too many problems!

Keep on laughing in the free world ....
