A certain episode...

I would like to ask if anyone knows a certain episode of Downtown doing an interview though I’m not sure if its Momusu or AKB48…

The episode was downtown being funny as usual and then there’s a certain "Scent Machine" that was being introduced by the group of which Matsumoto and Hamada tried to a great humorous effect… I watched it before though I can’t remember the keywords I used…
I’ve been looking for hours but I just can’t figure it out… :sweat:
Your feedback would be greatly appreciated… ^_^
