'Produce 101' has been doing product placement for drinkable vitamins and face packs as well as shoes, but apparently the most accidental one had the biggest impact.

The line was "Wow megaton bomb", and a couple of days after the show aired, convenience stores found themselves completely sold out of the ice cream 'Megaton Bar'.

Fans also found the situation hilarious and started making images of the ice cream with Kang Dong Ho as well.
