John Rich's Vegas antics kept him grounded in December 2011 -- the country singer was removed from a flight from Vegas headed back to Nashville because he was reportedly "not fit for travel." Translation: He was drunk. "Our employees are responsible for the safety and comfort of everyone on board a flight," Southwest Airlines spokeswoman Christi McNeill said. "If we can mitigate an uncomfortable situation prior to departure, it is our preference to do so, and that is what happened in this scenario." After sobering up, John took another flight home.
