the laugh, revealed

Lydia's laugh has surfaced in the last week or so. But today she had a full-on chuckle when Sonia set about entertaining her and Maya with some crazy noises. To be honest her laugh sort of reminds me of Arnold Horshack. See for yourself. Compare Lydia in the video to Arnold in this sound clip: http://tvland.classictvhits.com/WelcomeBackKotter/Sounds/WBKArnoldLaugh.wav
