Chris Pratt's prank phone call is Groot-iful

Chris Pratt has been known to improvise lines (including the best line ever on Parks and Recreation), so it shouldn't come as a surprise that he's a master prank caller.

The Guardians of the Galaxy Vol. 2 star showed off his skills during BBC Radio 1's "AlphabetCall," a bit where stars makes phony phone calls, with the added challenge of having each new sentence start with the next letter of the alphabet. Pratt's assignment? Call an exotic pet place in the UK, and ask about a Groot-like stick animal. Check it out.

Pratt not only successfully completes the call, but he also creates a Scottish grandfather character named Billy in the process. Bravo!

Of note: The woman working at the pet shop is so kind!
