Congratulations! It's a zeedonk! Well, actually a Shetland Pony gave birth to Zebra. What's next? Dogs and cats living together? Maybe, let's ask Doctor Peter Venkman:

Doctor Peter Venkman: This city is about to face a disaster of biblical proportions.
Mayor: What do you mean, "biblical?"
Doctor Raymond Stantz: We mean real wrath-of-God type stuff. Plagues, darkness--
Winston Zeddemore: The dead rising from the grave!
Doctor Egon Spengler: Forty years of darkness! Earthquakes, volcanoes--
Doctor Peter Venkman: Riots in the streets, dogs and cats living together, mass hysteria!

I'm staying in tonight.
