For those of you that didn't see it, Jim Callahan's act involved being temporarily possessed (with appropriate writhing and groaning) by a disembodied spirit, who communicated via "automatic writing" (i.e., the spirit using Jim's hand) the contents of a sealed chest. This he did correctly, and the spirit connection was subsequently "broken". After the performance, the host asked Geller for comment, and Geller was impressed (as usual). Then he asked Criss, who referred to the performance as "comical", then producing an envelope and offering a million dollars of his own money to Callahan and Geller if they could deduce its contents. Criss said "I don't want to hear about 'energy' or anything like that". Jim Callahan started objecting loudly and looked like he was about to lunge at Angel; the two were physically pulled apart and the program cut to commercial.
Earlier in the program, Geller made a joke about a magician (who used a pendulum to deduce the location of a target object) going into the oil-finding business; subsequently Angel made a retort that people "can't find water or oil by with divining rods or whatever".
