I actually can't find my specific version on YouTube but there's a station bumper for KNXT TV-2 in Los Angeles from the late 70s that has a "Here's 2 LA!!" cadence that I find myself just saying as a vocal tic to myself every now and then. Otherwise I really only have a very small amount of favorite bumpers/idents/logos that I like, which I know goes against the grain of most old TV nerds who seem to have an entire soliloquy about why the "V of Doom" scared them as a kid or whatever, but I just never cared as a kid so it was never anything that I thought about much. PBS's Funky Chimes kicks ass though. Though I guess that's not really an ident. The Hanna-Barbera swirling star one is though. That's pretty cool.
