16. Round The Twist
http://www.youtube.com/watch?v=mybg0l2Alaw "Have you ever... ever felt like this? When strange things happen, are you going around the twist?" Round The Twist was an Australian show about three children and their father who lived in a lighthouse and became involved in many bizarre magical adventures. It was fairly enjoyable in itself, but this exceptionally catchy theme tune was the best thing about it by far. Beginning airing in 1989, this show actually sporadically continued on and off until its eventual cutting in 2001. 15. Alvin & The Chipmunks
http://www.youtube.com/watch?v=UZRAARqgJeU Alvin and the Chipmunks ran from 1983 to 1990 and was about a singing trio of chipmunks and their adoptive father (and manager) Dave. The theme tune was sung in a very high pitch by the titular band and had a very addictive set of lyrics - what with the spelling out of the word "chipmunk" ("C-H-I-P-M-U-N-K!") and the very catchy "doo doo, doo-doo-doo-doo!" Simple but wonderful.
