I don't know if i'd call these two I'm mentioning my "favorites" but i do know they made an unforgettable impression on me!
The first one is Arnold & Kimberly are stuck across town and Kimberly not able to get a taxi,decides to hitch-hike. (In New York??!!) A man stops and picks them up but it certainly turns out to be the wrong man! He takes She and Arnold back to his place and ties upArnold w/ tape acrss his mouth. He then tries to put his moves on Kimberly. Arnold escapes and with help form the police gets back home,struggles to recall where he's been. Under hypnosis,he remembers the creeps license plate. They save Kimberly just in time! That certainly stopped me from ever hitch-hiking again!!!
Even scarier! Arnold and Dudley are nearly the next victims of a pedophile,who happens to be a bicycle-shop owner (played by WKRP's Gordon Jump). He lures unsuspecting kids to his special back room to watch TV (the kind not meant for kids). Arnold gets a look at what this "entertainment" is and leaves. Dudley stays behind but once again,Arnold,Mr. Drummond & the cops save the day.
Before that episode I never knew such people existed! I consider myself very fortunate.
I wonder why it is people who play one thing on TV don't live up to the things they say im real life?
