Boohbah is a television program designed by a bunch of British people. The show is intended to be an exercise show, but the execution is really poor.
The five alien-like abominations known as the Boohbahs don't communicate by talking. Instead, they fart. Farting is the #1 most used sound effect on this program. Don't believe me? Watch the show and take a shot every time you hear one. You might be dead within the first five minutes. Inbetween the "Boohbah" segments are literally the same thing you saw before, except with humans, a dog, and less farts. If you're looking for an exercising show for your preschooler, then I recommend you find something else. Or just turn off the television set.
