You see, Del Close was a horrible drunk and drug addict. He would slide into terrible patches in his life where he alienated everyone with his behavior. He was incredibly mean, vicious, irresponsible and just plain irritating to be around. Eventually, the theater where he worked would send him to rehab and he would come back humble and helpful.
Once, in the middle of a terrible downturn in his life, everyone at the theater hated him. They were all avoiding him and talking badly about him behind his back. Jim Belushi went up to him and said, "Del, I know everyone else here has a big problem with you, but I want you to know that I love and trust you."
Del looked up at him, "You trust me?"
The Belush said, "I do."
Del said, "You really trust me?"
Belushi said, "Yes."
Then Del Close kicked him as hard as he could in his nuts.
I have to admit that when I read the story the first thought I had was, Of course he kicked him in the nuts, it's Jim Belushi. Who wouldn't if they were that close?
