Since this has already been discussed - including Dickson's tweet - you probably don't want to start a relevancy debate over this. Someone choosing the first out of 4 results, when searching for a word is not a coincidence. That's the point! 18airbornecorps answering to Dickson's tweet is an interesting coincidence worth looking into. This gif alone is not. It's a rather predictable consequence.

Not to speak of the fact that Dickson has reminded everyone to drink their Ovaltine in 2019, too.
