US-ENTERTAINMENT-PREMIERE-PASSENGERSChris Pratt is a superhero when it comes to thinking on his feet.

The actor was out promoting Marvel's "Guardians of the Galaxy Vol. 2" when he was given a strange task on BBC Radio 1's "The Matt Edmondson Show." The host roped him in to making an AlphabetiCall, a prank phone call in which every sentence has to start with a different letter of the alphabet, in alphabetical order. Even more specifically, Pratt had to call a pet shop and ask them about stick insects given their similarities to Baby Groot, Vin Diesel's "Guardians" character.

The task might not sound that exciting, but Pratt's call turned out pretty great. He sounded a little robotic and a little bit pained, but he also managed to make sense in a very strange sort of way. It helped that he spoke with possibly the nicest person ever -- the woman never seemed to get suspicious or angry, and she stuck it out from A to Z.

Pratt appears next in "Guardians of the Galaxy Vol. 2," out on May 5.
