Dr. Demento

Dr. Demento (AKA Barret Eugene Hansen) is a disc jockey who achieved fame and/or infamy with his long-running syndicated radio program which features strange and bizarre novelty tunes of every type and description. Along with reviving popular interest in performers such as Spike Jones and Tom Lehrer, he introduced "Weird Al" Yankovic to the world, which is pretty much a lifetime achievement in itself.

The show continues to air weekly via the Internet.

He is reportedly one of BartSimpson's arch-enemies.

Tropes associated with the good Doctor:

 * Alliterative Name
 * Anti-Christmas Song
 * Bowdlerise: Tends to bleep out naughty words on his broadcasts.
 * The Cameo: Often turns up in Weird Al music-videos.
 * Christmas in July
 * Misattributed Song
 * Morally-Ambiguous Doctorate: Some of the songs he plays can probably cause brain damage.
 * No-Hit Wonder
