02E17 - Holiday

The next planet visited by SG-1 holds an unusual surprise: the only person by its star-gate is an old, sick man, known to Teal'c as Machello, since decades a famous adversary of the goa'uld, who even developed his own technology to fight them, was captured and tortured but escaped. He joins them to earth, but Daniel, who touched his recording device, wakes up in the dying body of Machello, which is only discovered after the alien walked of, given a clean bill of health by Dr. Fraiser, in Daniel's body, determined to enjoy life as an earthling, teaming up with homeless Fred, which soon turns bad... While Machello is searched, the others travel back to retrieve the device, but in the process Jack and Teal'c get body-switched too, and Sam fails to figure out on her own how to reverse it...
