Here are the sources for the 2 wonderful videotapes; it appears that both are still available.
1. The Theorem of Pythagoras is from the excellent Project Mathematics series by Tom M. Apostol and James F. Blinn done at Caltech. They produced modules on the Theorem of Pythagoras, The Story of Pi, Similarity, Polynomials, Sines and Cosines (3 parts), The Tunnel of Samos, Early History of Mathematics, and some teaching workshops. The work came out about 10 years agso.
The Theorem of Pythagoras uses animation and a witty voice-over for teaching the theorem. I show a 3-minute summary version (of the original 30 minutes) in the one-day course. The series of Project Mathematics tapes regularly brought the house down at the annual SIGGRAPH video show; these mathematical animations were glowing jewels among the over-produced, techy-commercial animations usually shown at SIGGRAPH.

2. The parody of scientific animations is The Viz-O-Matic: The Dangers of Glitziness and Other Visualization Faux Pas, done in 1993 at the Cornell Theory Center. This 2-minute tape appears to be still available from several sources: http://hulksmaash.imeem.com/video/o6PyqMpK/vizomatic/
Also Al Globus of NASA wrote a nice review of the tape.
