When people saying “Nothing’s impossible”, some people have a smarmy, stock response of “You can’t comb your hair with a brush, or brush your hair with a comb”. I think that’s funny, because it’s so wrong in a pedantic, literal sense, in the exact sense they think they’re being smart with. Comb and brush are both homonym’s for other words. comb = to look through. brush = to lightly touch against.

Originally, the gag involved showing the trees she’d fed from had turned into vampines, but it didn’t seem as funny as this.
