3. Arnold's Offered A Threesome (Timberly Loves Arnold, S5, E12a)
Seriously, this is one of the funniest moments in any TV show ever. The look of pure awkwardness, the blushing, it's almost like you're watching it happen. Fortunately you aren't, of course, it's still a kids show for crying out loud. Again, it's not exactly hidden, but another one of those references you miss as a kid and then cry laughing over as an adult (used in the loosest possible terms). As I mentioned already though, it's Arnold's reaction that makes the scene both priceless and comedy gold. Quite why the writer's felt the need to use that particularly terminology was clearly just for their own amusement, and once again it was a pretty blatant reference to sex in a kids show. But like I said earlier, it's funny as hell, so we'll let it slide. http://www.youtube.com/watch?v=JQ07BJKkuMg
