Re: above video, as noted by Cracked:

Check out the 40-second mark in the song, where Kermit sings longingly that: "rainbow's have nothing to hide," before telling whomever he's singing to, "wait and see, someday we'll find it, a rainbow connection." We'd stop there if it didn't get EVEN GAYER when he asks his muse, "Is this the sweet sound that calls the young sailors? ... I've heard it too many times to ignore it. It's something that I'm supposed to be." What ever could this "rainbow connection" be that "calls the young sailors" as well as the vagina-allergic Kermit? We'll let you decide.

Cracked magazine ran a hysterical piece on the state of queer children's characters post-Dumbledore. Though obviously meant for laughs, the article is actually pretty insightful, making queer cases for Kermit the Frog (sorry Miss Piggy), Dave Seville of Alvin and the Chipmunks, Velma of Scooby Doo, He-Man, the smurfs and the seven dwarfs..

This clip from Alvin certainly makes a clear case for Dave, as Cracked noted:

we find Dave sporting a killer tight shorts, long-sleeved sweater combo while antique shopping in a vaguely Middle Eastern looking location. You know ... business.
