Baljinda

 is the belief of a romantic relationship between Baljeet and Linda Flynn. It is commonly supported (albeit unseriously) as a crack pairing. It is among the most popular crack ships to date; it is just below Doofenshmirtz/Perry, Candace/Stacy, and Buford/Baljeet, but barely above Buford/Candace.

Proof
There is very little canon proof of this pairing. However, it has more than Ferb/Gretchen. Linda smiled at Baljeet in the episode "One Good Scare Oughtta Do It", and Baljeet smiled and waved back. In the same episode, Linda considers it very rude to think Baljeet is ugly; Hinting that she doesn't feel the same way about him. There was very little interaction and proof between them until the episode "Ask a Foolish Question", where Baljeet knows the perfect gift for Linda: A sliderule.
