One year to get into Guiness Book

[TheDudeAbides]

So my friend, father of Ryan Danger Goldberg , has got himself into another ridiculous prop bet and I'd like to help him out. He made a bet with another guy that he could break a world's record within one year's time. It doesn't matter what record it is, as long as he is able to officially break the existing record.

So I ask you OOT - what's his best plan? What record would likely be the easiest to break within a year?
