I remember seeing a movie as a kid, about a boy whose T-shirt gave him super strength, after it was used in some sort of experiment. Right before asking here to help identify it, I decided to give it one more try myself. Remembering that the T-shirt had a picture of a tiger on it did it for me: I found Sammy's Super T-Shirt.
Now my question is, do I still ask the question here (the source of the superpowers being some sort of experiment in a laboratory makes it (marginal) SF) and provide the answer myself, or is that frowned upon?
Note that my question is not whether the movie itself is SF enough to be on topic, but rather whether it's okay to ask and answer story-identification questions one already knows the answer to? Asking and answering in one go is allowed in general and the interface even has a special checkbox for it.
