Funny Animal Joke

I'm looking for jokes, usually bad jokes, that work as a series of short jokes were the punchline is in the final joke of the series.

Q: Whats the different between an elephant and a grape?
A: Grapes are purple

Not Funny

Q: What did Jane say when she say the elephant come over the hill?
A: "here come the elephants over the hill."

Stupid

Q" What did Jane say when she saw the grapes coming over the hill?
A: "here come the elephants over the hill."

Jane is color bline

Fucking hilarious. (though maybe not so much in this context.)

So, you see how this works? I've often seen many similar jokes that are continuation of the chicken crossing the road joke (often involving things being stamped to the chicken) or animals falling out of trees or whatever.

Again, the pattern should be Dumb Dumb, FUNNY. I'm not looking for a series of jokes that are all equally funny.
