And a cheap one too; You don't need to worry about feeding him because of the gag, and you don't need to go out anywhere, what with tying him to the chair.
Heck, you don't even need to worry about him changing the channel on the TV when you snuggle up together (or as much snuggling as you can do when one of you it tied up securely) since he can't get his hands free.
Yeah, pretty much a perfect date, even if he DIDN'T look like Dick Grayson (though that certainly helps)
