I still remember in my younger years when people had shipping wars over Trixie and Tootie, and saying that one of Timmy's future kids in Channel Chasers wearing glasses "wasn't enough evidence" to say if Timmy ended up with Tootie or Trixie.

I'm 90% sure one of the codes in Da Rulez was you can't wish for someone to fall in love with you. Now Timmy once loopholed this by wishing he was literally the last boy on Earth, but I'm fairly sure he can't force someone to like him.
