As a result of ABC and Jim Janicek's plan for Friday brand familiarity, definitive changes occurred to the lineup on Friday, September 22, 1989. An opening sequence for the two-hour block was introduced, featuring animated mice against a gray background. The theme music, featuring a male vocalist and a falsetto-tuned backup chorus, sang the lyrics, "Time for fun (thank goodness!)/Time for a good laugh (it's funny!)/Time, time, time, time for fun! (T-T-T-Time!)". The mice held up title cards containing the selected theme lyrics "Thank goodness" and "It's funny!" right in the way of an older mouse.. The sequence concludes with the older mouse breaking a grandfather clock with a mallet, which cut to the hosted interstitial.
