Is there a term for oxymoronic questions

I’m not even sure if oxymoronic question is a fitting nickname for what I’m asking because I’m genuinely unsure here. The questions I’m referring to are ones that ask something that’s almost an oxymoron, such as “what is the healthiest cigarette?” Or “who is the tallest dwarf?” Both questions have answers, but seem sort of contradictory in nature, considering cigarettes aren’t healthy and dwarves aren’t tall. It’d be nice if there was a term for such interesting sentences.
