A Tandy, a BASIC disk, and one bored kid (idea)

I remember in the early 80's, everytime I went to Radio Shack (which is the chain of stores that sold Tandy computers), there'd always be some computer running a BASIC program like this:

10 print "Radio Shack Sucks!!! ";
20 goto 10

I think bored 9 year old kids were probably responsible.
