|"You know what a greaser is? White trash with long greasy hair. You could use a bath, greaser. And a good working over. And we've got all night to do it. Give the kid a bath, David."|
|— Bob to Ponyboy in The Outsiders|
Robert "Bob" Sheldon was Cherry Valance's boyfriend. One night, when Ponyboy and Johnny are in the park, unwanted and alone, Bob and some other Socs come and pick a fight. Ponyboy smarts off to them, and they try to drown him. Furious and scared, Johnny kills Bob, the leader of the gang.
Bob drank often, and seemed to enjoy it. He got in trouble a lot because his parents never said no to him and blamed themselves. But, according to his best friend Randy, deep down, Bob was a good guy, and wanted someone to set limits for him and give him some firm ground to stand on, which was exactly the same thing all the Socs wanted as well.
He was killed by Johnny when he was trying to drown Ponyboy Curtis. Randy told Ponyboy that after Bob died, his mother had a nervous breakdown.
He was trying to drown Ponyboy with some of the other Socs in front of Johnny. Johnny became so scared, he stabbed Bob, killing him.
His death affected Cherry Valance and Randy, making Cherry not want to visit Johnny in the hospital, and Randy seemed to calm down and have a lower grudge against the greasers.
His full name was discovered by Ponyboy when looking through Sodapop's old yearbook.
