Ear Worm - "Take Your Mama", "I Don't Feel Like Dancin'", and all of Night Work.
Face of the Band - Jake Shears. Ana Matronic & Babydaddy are also popular. The latter is even considered a bear icon.
Del Marquis is actually quite popular himself.
Germans Love David Hasselhoff – Scissor Sisters have a small cult following in the United States, but frequently tops the charts in the UK, to the point that only three of their eleven singles have even been released as such stateside.
They even had a pair of Irish murderess sisters named after them. The women in question killed their mother's Kenyan boyfriend, sliced up his body (but not with scissors) and hid the pieces. His head was never recovered. The band were horrified by the association.
Harsher in Hindsight - "Mary" is about Jake Shears' platonic love for his friend Mary. The song itself sounds a bit mournful, though it was released in 2004. It was two years before she died of an aneursym.
Hate Dumb - Many people say they hate "Comfortably Numb", just because it's a cover. It Needs More Love.
