girl : where’s that? I’ve never been there?
guy : Oh you’ll see
annoying guy: (with pencil in hand) excuse me do you know where the pencil sharpener is?
guy 2 : Why yes I do, I believe it is upinya.
annoying guy: Oh then will you be a deer and point me in that direction?
guy 2: NO! Now go f@#k yourself
