I think Futurama was probably the first show that I became an avid fan of after Daria, to the point where I can watch my growing DVD collection daily without being bored.
Clearly I’ve been watching them so much that I noticed Fry had sung Walking on Sunshine on multiple episodes, or at least I had a hunch that he did. So with a little bit of research to clear any confusion, I found this awesome fan site/wiki and the details [my thoughts in brackets:
"Walking on Sunshine" is a song performed by Katrina and the Waves and released in 1985. On Futurama, the song remains a favourite of Philip J. Fry’s, despite only knowing the line "I’m walking on sunshine", after which he hums the rest. [LOL]
Four times have we seen Fry sing the song, three of which were in the shower. He even taught the song to his dog, Seymour Asses, back in (or sometime after) 1997, whom could bark the tune of the song (4ACV07). When Fry died in a dream sequence, it was performed at his funeral by Scruffy on bagpipes (4ACV12). Later, he uses it as a ring tone for his mobile phone (ItWGY)” -The infosphere.org
Haha.. I love this show.
