Well, I don't know about weird, but the top of my list for craziness has got to go to
ALL 3 Japanese Game Show tasks!
Just the whole atmosphere, with the Japanese audience and their enthusiasm, and of course the host. The Japanese are known for their love of Game Shows and this comes across in all three of these tasks.
If I was to choose the craziest though, it has to be Season 20 - catching the chicken whilst running on a treadmill...... I mean,
THEY'RE TRYING TO CATCH A HANGING RUBBER CHICKEN WHILE RUNNING ON A CONVEYOR BELT!!!!!! How in any way, can this ever be topped??!!
