Reggie or Not

Two aliens come to earth looking for somebody with a head full of knowledge, to drain for their own uses in taking over the planet. Enter the unsuspecting Reggie, who winds up trapped on their ship. The aliens, convinced that Reggie's friends might start to worry about him, decide to make a clone and send it back in his place. The only problem? The clone is nice...really nice. Archie isn't fooled by the imitation Reggie for a minute, but the rest of the gang are pleased with his ""change of heart""...until they discover the truth.
