* BigLippedAlligatorMoment: Karl rides with a bus full of Israelis who pile out at stoplights and dance among the traffic. Effectively, it's a group that lives to cause [=BLAMs=] in the lives of random motorists.
** To the point where Karl seemingly becomes so frustrated, he makes a run for it.
* DudeNotFunny: Some of the things that Ricky and Steven make Karl go through is a bit much, to the point where you actually start to feel really bad for Karl. There is a fine line between 'cruel, yet funny' and just plain 'cruel', and they occasionally cross it.
** Special mention goes to when they force him to stay in a really run-down hotel near the Taj Mahal, calling it a "honeymoon suite", knowing full well that he's been very ill and hasn't slept for over a day. The smell is unbearable and he nearly walks out. Plus some of the "activities" like kidnapping scenarios and shark-caging.
* EarWorm: "Seven Wonders" in the Series 1 soundtrack.
