Watch: Will Arnett Prank Calls a Toy Shop as LEGO BATMAN

Will Arnett performs one of the most challenging prank phone calls I've ever seen in this great video. Arnett appeared on BBC 1 Radio in character as Lego Batman to promote The LEGO Batman Movie and ends up prank calling a toy shop, but there's a twist. Batman must begin every sentence with the next letter of the alphabet all the way through! You'd think it'd be challenging, but Arnett doesn't seem to struggle too much. Maybe he's a master of improv, or he probably has a script that's helping him out as he goes. I laughed either way so great work Will!
