I had long hair when I was in kindergarden, and of course it is very painful with the knots in the hair. My parents would mention 'rats in my hair' etc.
So I ended up making a mouse trap in hopes to keep the rats from attacking my hair. The trap had copied the box-and-bait under it trap you see on Looney Tunes.
My parents still won't let me live it down.
