"We'll do what we do every night, lil' chum!" he said in his usual stupid, overdramatic impression of Batman (where did he even get it from?). "Unearth the dastardly detritus on the forest floor of evil and expose it to the light of day!"

He pointed ahead with his hand, pretending he was holding a grappling hook shooter like Tim and made a "kch-chkoosh" noise with his mouth like he was shooting a line to a nearby building.

Then he started flying in a way that made it look as if he was swinging from an imaginary grappling line.

"Whoosh! Batman, awaaaaay!"
