Dog Bean Song

Have at least one accomplice that has a dog name ready.

You should pronounce 'been' formally like 'bean'.
If you start with less obvious names and work towards the obvious, it may take new guys longer to figure out the joke.

My dog Rover likes to roam
One day Rover left his home
He came back, nice and clean
Where oh where had Rover been?
Rover been, Rover been
Where oh where had Rover been?

[Say this part]
Hey, Joe! (or Bob or Larry or ...)
Yeah?
Do you have a dog?
Yeah!
What's your dog's name?
Jelly!

Joe's dog Jelly likes to roam
One day Jelly left his home
He came back, nice and clean
Where oh where had Jelly bean?
Jelly bean, Jelly bean
Where oh where had Jelly bean?
