Al, a salesman, and his ten-year-old son, Bob, moved to a new neighborhood. Carl, Dave, and Ed, neighborhood children of Bob's age, saw Bob riding his skateboard down the street and stopped him to see if he would be a "good sport." They began to call him names and when Bob tried to leave, Carl put his foot on the skateboard, preventing him from leaving. Bob began to runhome and Dave threw a stick at Bob which hit Frank, Al's neighbor, and fell onto Al's hedge. The three boys then threw rocks at Bob and one stone grazed Bob's shoulder but did not injure him. Al came out and the children taunted him by calling "pig, pig, pig, pig."1. As to the stopping of the skateboard, for which of the following intentional torts is Carl most likely liable?
