Yeah this kind of casual title is very rare, and it’s always just a small addition to an otherwise straightforward title. No one would allow for a purely cheeky title and no author would want one anyway. The first thing people use to judge the relevance of your paper is the title. If it’s not immediately obvious what it’s about, they’re not going to look further. Immediately obvious for someone in a related field, anyway.
