Will Arnett made an amazing prank phone call in this hilarious video. Arnett recently appeared on BBC 1 Radio in character as Lego Batman to promote The LEGO Batman Movie and as a challenge, he called a toy shop as the Batman, but there’s a twist. Batman must begin every sentence with the next letter of the alphabet all the way through! It is way more easier for him to do but it is hilarious every step of the way. check out the video below.
