Proof of elephants in alternate dimensions

My son woke me in the middle of the night last night. Because he did, I can remember vividly what I was dreaming about. The dream itself isn't important, but the joke was too good (bad) not to pass on. I was telling a joke. It's not one I know, so it was new to me. (!?)

What do you get when you cross an elephant with a rhino?

The answer must be said aloud for full effect- "Elephino"....

('ell if I know?) get it???

Could be my subconscious run amok. Could be proof of elephants in other dimensions.

;) Whatever, I hope it made you laugh!
