A childhood belief about names

This was a few years ago, but.. anyway. My niece had just come home from pre-school and was telling myself and my mom about her friend "rizzerbeff". My mom and I were completely stumped. WE thought her friend's name was "Lizard Breath". "Rrrriiiizzzzzzzzerbefffffff" my niece said, slowly, so maybe we'd catch on. All the while, my dad was chuckling as he was listening. He leans down "sam, was her name Elizabeth?" and my niece immidiatly starts nodding "yeah papa, rizzerbeff". We still laugh whe we talk about that, only my niece gets kinda mad....oh well..:P
