Fred Rogers, host of the beloved children's television show, Mr. Rogers Neighborhood, wasn't always the friendly, gentle soul he appeared to be. During the Vietnam War, he was a sharpshooter for either the Marines or the Navy SEALs, with a record 150 "kills" during his service. Why do you think he always wore sweaters on his show? To cover up all his military tattoos. The dude was hardcore. IS IT TRUE?: Not even close. The Navy SEALs addressed the rumors directly on their website. In their words: "We have to state it is false."
