Chris Pratt was asked to make a prank phone call, and he delivered in a big way.

The “Guardians of the Galaxy” star took part in a recurring segment called AlphabetiCall on BBC Radio 1’s “The Matt Edmondson Show.”

It involves making a prank call, where you start the first sentence with a word beginning with the letter “A” and each sentence after with the next letters of the alphabet.

Pratt called a pet store to ask about caring for his stick insect... but as the call went on, his “pet” sounded less like a bug and more like“Guardians of the Galaxy” favorite Groot.
