I’m Gonna Kill Myself

Sammy’s expression when he’s frustrated is: “I’m gonna kill myself”.  Among other things, he gets frustrated when he loses to Dad in chess (who Sammy cannot accept can beat him in chess). 

When Sammy loses: “I’m so dumb, I can’t beat anybody in chess. I’m gonna kill myself.” 

One day during lunch he got upset because he c, got off his chair and claimed: “I’m gonna kill myself now. I’ll go to the gunshop and kill myself.”
