Why did the music teacher need a ladder?

To reach the high notes.

I was at the park with my kids, and we saw a guy playing fetch with his dog. The dog was really fast and could catch the ball in mid-air. I was impressed and asked the owner how he trained his dog to be so agile.

He said it was a paws-itive reinforcement

So I was trying to fix a squeaky door hinge in the house today, and my son came over to watch. He asked me why the door was making such a loud noise every time I opened it.

I told him it was because the door was feeling unhinged!

Why did the bicycle fall over?

Because it was two tired!
