A San Francisco man is facing a charge of interfering with the duties of a flight attendant after becoming unruly aboard a cross country flight that had to be diverted to Pittsburgh.  Thirty year old Kinman Chan allegedly fought with crew members aboard a flight from Philadelphia to Los Angeles.  Crew members said he made odd gestures before entering the plane's restroom shortly after takeoff and began to scream.  When he exited the restroom the crew tried to get him to sit down, at which point he began to fight them and had to be subdued with a choke hold.  His defense?  He claims he was high after eating marijuana cookies.  Isn't marijuana supposed to relax you?  I've never seen a headline that reads, "Man Smokes Pot, Goes on Violent Rampage."  It's more likely you'd see the headline, "Man Smokes Pot, Eats Doritos, Falls Asleep."
