Could You Demonstrate That Once More, Please?

Alex was in a creative mood yesterday: he told us how he had to call the police on Catherine's mom because she crawled under the couch and punched him in the eye when he wasn't looking-- "she sneaked up on me and when I was turned the other way she went like this . . ." and then he would pretend to punch himself in th eye, which we got him to do over and over by saying, "Wait, how did she do it? (and I think Catherine's mom was upset that he was making up this awful story about her, but we found it hysterical).
