Actually, when the show moved back to syndication, and later CBS, There was a different 20-sec. opening. This is the one currently in use, and it differs from the 20-sec. version that was once seen on DC/TD in 2002-2003. IIRC, I thought I had seen the 30-second version of the song on ABC airings too, If the long version did air on ABC, it was probably for a very short time. To be fair, I have seen the long version on YT, and I always assumed it was for international airings.
The only reason I watched this block (KOL/KEWLopolis) was because of this show (Cake). It was sad that it only got a single season, perhaps nowadays, when people look back on this program, the only actress they'll probably remember from that show is Anna Marie Perez De Tangle, who is now a famous Disney Channel star.
