Oggy oggy oggy!

A good way to warm up the campfire's voices is with a yell or two... in this one, the campfire leader does the 'oggy' bits and the campfire do the 'oy' bits.

Oggy Oggy Oggy!
                                    Oy Oy Oy!
Oggy Oggy Oggy!
                                    Oy Oy Oy!
Oggy!
                                    Oy!
Oggy!
                                    Oy!
Oggy Oggy Oggy!
                                    Oy Oy Oy!

We also use the 'AA Milne' versions of this...

                                    Bounce Bounce Bounce!

I tend to use these near the beginning of the campfire if I don't seem to be getting much noise out of the circle; they are easy, and nobody has a problem remembering the words!
