Binkie is going as Batpug:

Meanwhile I think I should go as a sexy thing that should never ever be sexy.

Perhaps a canned ham in lingerie.

Or a sexy 24-pack of Charmin Ultra Soft

Or a mustard packet that’s also a very short skirt.

Then I’ll go to a major Halloween event and strut my stuff. But then those people who take that shit seriously will probably not get the joke.
