Green Acres (1965)

S6E18 Star Witness

When the Ziffels catch the flu, Arnold the pig spends a few days with the Douglases, bringing along his luggage and ukulele. While waiting in the car during an errand in Pixley, Arnold witnesses a bank robbery and takes note of the thieves' appearance. However, his excited squealing leaves him voiceless, preventing him from sharing what he saw with the sheriff. Mr. Haney pitches a witness protection plan for Arnold, while Mr. Kimball, trying to track the criminals, inadvertently reveals Arnold's location. The robbers mistakenly kidnap Eb, thinking he's Arnold. In a twist, Arnold leads the Douglases to the hideout and helps capture the crooks by knocking a ladder onto them, earning a $2500 reward.
