Since today is Reed Alexander's 20th birthday and Transformation Tuesday ("You'll rue the day!"), we decided to take a trip down memory lane with one of our fave Nickelodeon shows of all time and see how much each actor has grown up. You won't believe how much they have changed since they first started the show!
