Lisa and Lisa's Mom in “Unfinished Business”

Mom, can I get some new sneakers, please?

Whatever for? Yours are still in good shape.

But they don't even compare to Moppy's. He got all this neat stuff on his sneakers. Mine are just so boring!

[thinking Lisa is trying to follow the crowd after she saw Moppy's new sneakers] You shouldn't place so much weight on appearances. [thinks Lisa is better off not following the crowd] Your sneakers are perfectly fine.

You mean perfectly plain!
