Here are a list of ships I like that involve two canon characters!
1. Lisa × Nelson
(I just find it cute that Nelson defended Lisa in many episodes)
2. Julio × Otto
(They just look cute together!)
3. Edna × Skinner
(I wished Edna ended up with Skinner but he chickened out and lefted her :( .)
4. Marge × Homer
(Even if they are married I still ship it, it was meant to be)
5. Mr. Burns × Smithers
(If only Mr. Burns loved Smithers back)
