Call and Response Ideas

I read this short article that lists 50 call and response ideas to get kids attention.  My favorites from this article are:

• Flat tire…Shhh!
• Can I get a…Whoop whoop!
• Hands on top…Everybody stop! [while putting both hands on head]
• Are you ready, kids?…Aye Aye, Captain!
• Sports Themed:  DaDaDaDa...Go, Pack, Go!

Please share your favorite.
