My brother used to tell me stories about how he was a super spy with a companion dog that mom and dad didn't know about. The spy missions (including one involving evil Lego), the death of super dog, everything. Of course, I shouldn't be suprised: he used to pretend to be on the phone with the tooth fairy! I believed every word he said for a long while.....
