The problem is that when I was younger, I'm 47, Bongo Bongo land was a dismissive racist insult towards Africa and its people.
It still is used around pubs, as such.
People deliberately don't try to pronounce Arabic names and tray the whole spoken culture as gibberish.
When Um Bongo and the adverts came out (""way down deep in the middle of the Congo""), anyone who was mixed heritage (which I am) had it sung to them, when as said the Bongo drum was from Cuba.
Plays on words are one thing, a lot of the Show is done cleverly, it's a shame that other bits had to be in there.
When there was a survey done about casual racism in schools, a lot of the children sites the piss taking of their name as something really hurtful.
