There are some emus around here, I think the people had the same idea as you r uncle Herman. I always thought they reminded me of Dr. Doolittle's Pushmepullyous.
No, Emu's are birds and Pushmepullyou's were like two Llamas joined in the middle with heads facing different directions!Silly boy!
Like this:emuPush-me-pull-you
Ohyeah, it was the Llamas I was thinking about, them animals they make boots out of.
These? Yeah they are cool. I liked the two toned.
