When you give someone muscle relaxants instead of a rufie. Then you rape them while they're still fully awake, but unable to resist.
"Uh oh, I can't move my arms or legs... did you put something in my drink?"
"Yup, and it looks like it's kicking in, so now I'm going to drag you out back and give you a Jack's Mannequin"
"God damnit! Why can't you just slip girls rufies like everyone else, you sadistic bastard?"

The amazing side-project of Something Corporate's front man, Andrew McMahon. Everything In Transit, "A concept album exploring his return to the hometown he left to pursue his music career with Something Corporate". The album was released on August 23, 2005. The songs are amazingly written and everyone can find someting to relate to. Buy the CD!!

A side project of singer/songwriter Andrew Mcmahon. Basicaly a solo project produced from the help of many other people including Tommy Lee on drums! Mcmahon uses his unique voice, powerful lyrics, and the heartfelt rithyms of his ever so famous piano. With a full album out now they are a great band to listen to whether your happy or sad. Basically Something Corporate with a little twist of pop flavor. For more info see Andrew Mcmahon or Something Corporate.
One hell of a kick ass side project sure to rock you. Jacks Mannequin is awsome

Piano Rock, to rock out on a grand piano, upright or keyboard. Kicking over your bench or seat and pounding some ivorys. A Jack's Mannequin might also exhibit the compulsion to dance on a piano.
That band is trying to play some Jack's Mannequin
