If you were hoping to see Benedict Cumberbatch stretch his comedy muscle ahead of this weekend’s Saturday Night Live, look no further than The Tonight Show‘s eggs-cellent “Mad Lib Theater.”

In the sketch, filmdom’s Doctor Strange plays a detective with a truly bizarre accent (we’re picking up hints of Mark Wahlberg and The Big Bang Theory‘s Barry Kripke) who interrogates a thief (Jimmy Fallon) suspected of stealing more than 4,000 of a certain item from a department store.

Not to worry: Fallon breaks character right on cue, lasting just 15 seconds into the bit comprised of random verbs and adjectives — solicited ahead of time at the start of the segment, Mad Libs-style — before a case of the giggles emerge. As they say, some things just never change.

Press PLAY on the clip above to watch the unconventional interrogation (which officially begins at the 3:29 mark).
