@Barclayss Obviously it involved losing a bet. What we don't know are the exact terms of that bet:
1) If Nishikata loses, Takagi gets to tie him down and $$$$ him
2) If Nishikata loses, he has to $$$$ into a cup in front of a live studio audience and then Takagi runs away with it to a fertility clinic
3) If Nishikata loses, Takagi goes on a four-week vacation with several male gymnasts who have MENSA memberships
But however it worked, Nishikata lost, Takagi got fertilized and now we have Chi! God bless.
