We have several
"Wanna go outside?"
"Daddy's Home"
"Want to go to the mailbox?"
if i am packaging up an order to mail, they know they get to go in the car to the mailbox and they start twirling.
"Want a carrot?"
"Want a treat?"
"I need to take your picture!" I pick out the size girl i need for a photo and they all get some cheese whether they posed or not. They all want to pose since they get first bite!
"Where's your brother?"
"Wanna go for a walk?"
"Go get that squirrel, birdie, or kitty!" - they all run outside like maniacs!
If i put on shoes, they go nuts thinking that they get to go somewhere unless i say, "I am going to the store" and they know they don't get to go there so they just lay back down.

They are all soooooooooooooooooo smart!!
