You didn't think I would do Budapest or Balaton for B, right? Give me some credit, people.
I have something much better:
The TV Bear.
Tévémaci (TVBear) for the long years of my childhood was the character that announced that it was time for the evening cartoon. Thus:
(Yes indeed, Dear Visitor, that was a naked bear in a shower. You are welcome.)
And, once the cartoon of the day (which had nothing to do with the bear whatsoever) had concluded, the TV Bear dutifully told us that it was time to go to bed. Observe:
There is also an extended version of the video that includes a crucial moment in TV Bear history: The brushing of teeth (or fangs, I assume):
This is the version that gave birth to the popular colloquial expression in Hungary: "The Bear has spit, it's time to go to bed." Or, alternately and quite ominously: "The Bear has spit for me."
(Extended side note: In Hungarian, "spitting" also stands for "snitching," so in post-socialist Hungary the common joke is, "Why did the TV Bear go off the air?" "Because he spat." Post-socialist humor. Gotta love it.)
