Continuity mistake: When Doctor Strange attempts to use the Time Stone on Ebony Maw, Maw ties up Strange telepathically and strangles him unconscious. Beside Strange is a police car and a motorbike tipped on its side. Maw then lifts the ground he is lying on, but the police car has been replaced by an SUV and the motorbike has disappeared. The shadows also change. (00:23:25)
Peter Quill: Dude, don't call us plucky. We don't know what it means. We're more optimistic, yes. I like your plan. Except, it sucks. So let me do the plan and that way it might be really good.
Drax: Tell him about the dance-off to save the Universe.
Tony Stark: What dance-off?
Peter Quill: It's not a thing.
Peter Parker: Like in Footloose, the movie?
Peter Quill: Exactly like Footloose. Is it still the greatest movie in history?
Peter Parker: It never was.
Tony Stark: Don't encourage Flash Gordon.
Peter Quill: Flash Gordon? That's a compliment. Don't forget, I'm half human. So that 50% of me that's stupid that's 100% you.
Trivia: Kenneth Branagh, director of the first Thor movie, has an audio cameo. He's the one voicing the distress call from the Asgardians which the Guardians of the Galaxy pick up.
Question: Why doesn't anyone ever destroy the stones? What purpose do they serve other than no one person should have them?
Answer: "Doctor Strange" demonstrates that the Infinity Stones are useful in the most dire of situations, when Strange used the Time Stone to prevent Dormammu from taking over the Earth. It's also possible that some of the stones are indestructible. Wanda is able to temporarily destroy the Mind Stone by using her own powers, but the Power Stone will destroy any being that doesn't possess the strength to wield it, and the Reality Stone is shown to have a will of its own and defended itself when it bonded with Jane Foster.

Also, in the comics, if the stones are destroyed they will simply be replaced by something else or even stones again. They represent the existence of the universe and cannot be destroyed for real. Always only temporarily.
