Neil deGrasse Tyson’s plan to get Donald Trump’s attention can only be described in one word: gripping.

The astrophysicist joked Friday he’d need to make a bold move to get the president-elect to engage in science talk. Like grabbing him by the crotch, for instance:

When I meet President Trump, I may first grab his crotch -- to get his attention -- then discuss Science with him. — Neil deGrasse Tyson (@neiltyson) November 18, 2016

Don’t worry, we’re pretty sure Tyson is joking. (The tweet is a clear reference to a recording released in October of the president-elect bragging about groping women by the genitals.)

“When you’re a star,” Trump says in the audio (and to be clear, by “star” he means himself, not a celestial body), “they let you do it.”

Tyson has happily riffed on slogans Trump has popularized. Following the election last week, Tyson appeared on “The Late Show with Stephen Colbert” and suggested a new mission for the country: “make America smart again.”
