I LOVE frogs and so I had to find a joke to add: What's the difference between a cat and a frog? A Cat has nine lives but a Frog croaks every night! source: http://www.jokes4us.com/animaljokes/frogjokes.html
Not quite a joke, but we have "frog" stitches in knitting/sewing/crocheting ... Rip-it, Rip-it. Seriously. That's what they're called! And I'm an expert at them.
