And yet, the transformation is only skin deep...

...when she saw the previous post, Buttercup immediately launched into this:

Yeah, Mom, but when Dad gets back, he's going to say one Bart-joke and I'll be gone. 

Then she proceeds to recite the following, verbatim:

Moe: Hello, Moe's Tavern. Birthplace of the Rob Roy.
Bart: Is Seymour there? Last name Butz.
Moe: Just a sec. Hey, is there a Butz here? Seymour Butz? Hey, everybody! I wanna see more butts!

At that point, she cracked herself up to the point that she could no longer speak.

Pretty on the outside and Bart Simpson on the inside...I guess it could be worse!
