Senior temporarily puts aside his feud with estranged son Junior on 'American Chopper: Senior vs. Junior' (Thu, 9PM ET on TLC), calling him to offer support after a roofer fell to his death at Junior's shop.

The 26-year-old worker, who had been hired by the landlord of the building, stepped backward into a hole in the roof, fell 40 feet and died from his injuries.

"I heard about the incident the other day," Senior said. "I guess the important thing is that you and Mikey are okay. If there's anything I can do to help out, just give me a call."
