In front of Bart was ... there was really no better way to describe him than 'giant, talking kangaroo'. In an instant, all annoyance diffused into the air; an awe replacing it instead, "Whooooa."

He picked himself up, helping to peel the clothing off too. Soon -- maybe a little too soon -- all the clothing is nicely stuffed into the washer, and Bart continues talking.

"I've never seen a kangaroo use a washing machine."

He could be asking why a kangaroo was talking to him at all, but alternate universes aren't exactly a first for him. Once you've seen everyone around you turn into gorillas, a talking kangaroo or ten doesn't really faze.
