Howard took a call from Dennis, one of Sal's close friends, who revealed that Sal hadn't made the giant paper mache boulder for his son's Indiana Jones-themed birthday party on his own.
Sal came in to confirm the story: "I made it with him. I got the supplies, I helped him the best I could." Howard laughed that no one should be trying to take credit: "I saw this boulder. The two of you would flunk a fifth-grade art class."
Dennis then began ranting about Sal not giving him credit, but Howard tired quickly and hung up: "Dennis, we get it. We're very sorry for you." Exasperated, Howard turned to Sal: "Man. Your friends. Some life you've got there."
