Zachary Quinto pranks Jesse Tyler Fergsuson, gives his Benedict Cumberbatch impression: Watch

What happens when you get Zachary Quinto and his "Margin Call" costar/close friend Susan Blackwell together for a sleepover? Hint: it involves prank calls.

The pair did an interview for Blackwell's Broadway.com segment Side By Side, and it involved a whole lot of adorableness while discussing Quinto's recent adventures, which include "American Horror Story," "Star Trek Into Darkness" and "Sesame Street." 

The best moment comes when Blackwell and Quinto prank call Jesse Tyler Ferguson and pretend he has ordered a stripper for his Tie The Knot pop-up shop. Also being pranked is "Smash" actor Christian Borle, who recently appeared in "The Sound of Music Live!"

Later in the interview, Ferguson texts Quinto back. "Was that Cherry Jones?" the "Modern Family" star asks of Quinto's "The Glass Menagerie" Broadway costar.

Blackwell seems to be as big a Benedict Cumberbatch fan as the rest of us, and admits that if she were to have him on her show, she would just have him say "words." At this point, Quinto offers up a pretty spot-on Cumberbatch impression and simply says, "Tumescent." That's why he gets the big bucks, people.

Of the weirdness on "American Horror Story," Quinto says, "It's kind of like another day at the office, just because there's so many technical considerations that go into a show like that." As for the weirdest thing he's ever had to do for the FX show, he says, "Have sex with a corpse. They covered her in this gel. It was nasty; it was gross. ... There was a corpse double."
