Halloween Hunger

Joker: "Trick or treat!  Smell my feet!  Give me something good to eat!  Ah ha!  Ha!  Ha!  Haaaa!" 
(Bonus points if you read that in the voice of Mark Hamill's Joker)

Fat Man and Batman

After the disappearance of the ball, a time-out was called during the annual DC Kick Ball Tournament to determine if the Penguin was secretly concealing it under his shirt or if he was really that fat.

No Capes!

"Ah, Batman, how about we go without our capes the next time it's windy out?"

Creepy Penguin

"I see your umbrella is a bit small.  Here, come under my multicolored umbrella with me, my dear."

Big Ring

"I'm telling you, Barry, I think I overcharged my ring, and this is the only part of my body that it will fit on!"
