Bad Luck Brian: "Does my butt look big in this?" - "Yes ma'am." "I want to sleep on the left side!" - "You're Right." "Are you happy you married me?" - "I'm sorry."
When I noticed this, and tried looking for the answer, I noticed the title of the piece is actually "Nanna nanna bat man". Note how Batman is shown by the two nouns that make up the name, and (therefor) lack of a capital "B". Perhaps (and this is just me speculating paranoidly as usual) he did this in order not to get into any legal trouble.
Now, as to why there is a symbol in the other picture...Redditors might have done that, just like they added more nanna's to get the entire theme right: More nanna's.
Fun Fact: The (original) picture Kevin finds of "Buzz's girlfriend" was a picture of a boy made up to look like a girl because Chris Columbus thought it would be too cruel to make fun of a girl like that. The boy that was used in the photo was the art director's son.

"Are you happy you married me?" - "I'm sorry."
Foolproof, Alex ;)
