Self join, you say? I'm going to join the party and make it a double self join - that'll really show those duplicate names who's boss!

RIGHT OUTER JOIN with self join? Sounds like a dance move from the 80s. I'll stick with the classics, thank you very much.

Subquery, eh? Sounds like a sneaky way to get the job done. I like it, but I'm also not afraid to get my hands dirty with a good old self join.

Wait, what's a PULL OUTER JOIN? Is that like a superhero move or something? I'm sticking with the good old self join.
