Some other quotes:
Did you ever fly a kite in bed?
Did you ever walk with ten cats on your head?
Do you know how to milk this kind of cow?
We can do it, since we know how.
If you've never done these things, you should.
These things are fun, and fun is good.
There and here, here and there
Funny things are everywhere.
