Me too, it gave me back weird memories when someone posted weird ships on a SB community on Google+ such as SpongeBob x Mrs Tentacles or Mr Krabs x Gary......I at first thought it was about shipping, huh
Okay, on the topic. Actually, I quite like SpongeBob+Patrick and SB+Squidward.
I really like how SB and Patrick such a good friends most of the time, Patrick can be a jerk sometimes due a bad writing or something else, but when episode is well-written, their dynamic is really cute and believable.
I really enjoy Squidward and SpongeBob for many reasons, but most of all - because it's hilarious.
Also I like when Mr.Krabs and Plankton have dynamic like in "Best Frenemies", when they hate each other, but can't live without their rivalry, because it's so enjoyable to them.
