Did this come straight from Deadpool?
The scene where he's timescrolling in a fourth wall break and slows to the pony in one hand while 'shaking hands with himself' and then says 'all caught up' is just this.
Denis Leary (I think?) made a joke decades ago about searching for 'goats on fire' pron, and the search engine asks 'which species of goat' in return.
Nothing new here. People have kinks.
