I haven't seen this show for over 20 years, but i can remember in one episode, Dick was on the trail of some-one or other, and his investigations lead him to a shady looking Chinese laundry. he started to grill the workers for information but they didn't want to play. so a punch up started. fists flew, wheels spun ( remember Dick Spanner is a robot) Our hero in a desperate move decides to head butt the laundry workers and then hightail it down an alley. and in the movie classic time saving method of the spinning newspaper headlines. it read "SPANNER NUTS WASHERS AND BOLTS". they just don't write stuff like that anymore. i'm sad to hear that its not available on video or DVD. 6 july 2008, found it on DVD, helped me pass the time in afghanistan.
