There have been countless biographies, auto-biographies and documentaries about one of the most famous rock bands in the history of your face. But there are facts out there some fans might not know about the Rolling Stones.

1. The band would play with an inflatable penis on stage. The giant phallus even had its own nickname.

On the band's "Tour of the Americas 75" there was a giant inflatable penis on stage. They nicknamed the giant phallus "Old Grandfather" because they found it difficult to keep it erect. Sometimes Jagger would ride the penis while other times he would just attack it until it deflated. Apparently the penis wasn't welcome at all concert stops. Rolling Stone Magazine published a concert review in 1975, where the band was informed by Memphis police that they would be arrested if the penis showed up. Since they didn't use the inflatable outdoors and this was at the open-air Memphis Memorial Stadium, it didn't become a problem.

2. Carrie Fisher has implied that she and Harrison Ford were drunk while filming a scene from "Empire Strikes Back," thanks to partying with the Rolling Stones the night before.

Back in 1999, Fisher wrote a piece for Newsweek recalling times she spent filming the original Star Wars trilogy. Fisher wrote about staying at Eric Idle from Monty Python's townhouse for the "Empire Strikes Back" shooting. After he wrapped filming on "Life of Brian," Idle returned home and brought back a highly alcoholic drink which he said was given to the extras to make them work longer. Fisher nicknamed it Tunisian Table Cleaner.

A makeshift party started with Ford, Fisher, Idle and The Rolling Stones, which led to the two "Star Wars" actors staying up all night. Fisher claimed she and Ford had drank so much with the Stones that they were hungover to film the arrival at Cloud City. Crazy huh?

3. Keith Richards once momentarily stopped playing at a concert to whack a stage rusher in the head.

While performing at Virginia's Hampton Coliseum back in 1981, an idiot fan rushed the stage. And never missing a beat Keith took his guitar off and swung striking the fan in the head. Security was right behind the idiot and rushed him off the stage. In one motion, Richards removed his guitar, hit the fan in the head and put his guitar back on and continued playing. It's almost as if were choreographed but it most certainly was not.

4. The Rolling Stones are credited with popularizing the Tequila Sunrise, by telling bartenders across the country how to make it while on tour.

Writer Jeff Burkhart explained how in 1972, the band was introduced to the then virtually unknown cocktail during a private party at the Trident restaurant in Sausalito, California. After this introduction, the band began to order the drink at bars all across America during a string of shows that was unofficially known to the band as the Cocaine and Tequila Sunrise Tour, as detailed in Keith Richards' book, Life.

5. Mick Jagger bit off part of his tongue while younger, which altered his voice from "posh" to the iconic, rougher timbre he's now known for.

A 1981 issue of New York Magazine claimed that Jagger started to sound like the American rhythm-and-blues singers he admired after he bit off part of his tongue in a fall. The incident has been brought up many times over the years, but the exact details remain hazy -- for example, some say it was a basketball injury while growing up, while it's also been said to have happened during a gymnastics accident. Regardless, in 1971 the band's now iconic "Tongue and Lip Design" debuted, which certainly proves Jagger's at least a little bit proud of what's inside his famously large mouth.
