Sheldon: Leonard, if you had food on your face, would you want me to tell you?
Leonard: Where? Did I get it?
Sheldon: Oh, no, not now; it was last week. I didn't know whether or not to tell you, but everyone was staring. For the record, it was right there. And it was Nutella.
Leonard: Thanks.
Sheldon: You looked like a hazelnut Hitler.
