This reminds me of the "Wheel... of Money" parody by WKUK
Every time they cut to commercial or came back from it, the audience had to get a new reminder or instruction from the host on how the way they were chanting "Wheel... Of... Money" was just too similar to another gameshow's name, and the legal team was advising that they would have to chant the name a different way.
So it became "Wheel... [awkward even longer pause] Of Money! [second phrase in all one breath without pausing]"
The contestants also had a problem remembering to let go of the wheel when they spun it, and by the end of the skit all of them had both their arms torn off by the spinning wheel.
I think for the Futurama Birthday song, they probably got away with it, given it was also a parody it has probably hit multiple bullet points on the checklist of whether it should qualify as meeting standards for fair use.
