In the beginning of the show when the three of them get on the ship a board listing the activities on the ship is in the background and Tantric Origami is the last item on the list. Thank goodness I wasn't drinking milk at the time!
I'm not going to go into detail what Tantric is but it seemed to me a bit inappropriate for the show. I found it HILARIOUS (and yes there is such a thing)
In the past when risqué items popped up in kids shows some people say well you should be watching the show and monitoring the TV the kids watch.
I do the TV is in the living room. I've watched dozens of episodes. The episode in question was rated TV-G. So "V-Chip" censorship and even parental monitoring is out. So when I see about a dozen episodes and they are vanilla and such it should be safe to say it's OK to watch.
OK yes the joke was a TINY one and was tough to notice (this is the second time I've seen this episode) but how bold will they get.
Personally I would LOVE to see the brothers start to expand their show a LITTLE BIT into some issues (After School Specialesque) and allow parents to discuss with their kids the content.
But Tatric Origami? That just made me giggle!
