Oliver's New Expression

A week or two back (Wha...?? It's already June??) Oliver developed a new facial expression. He kind of lifts his eyebrows, and squints his eyes, and does his usual open-mouthed smile. He does it for practically any reason (and especially when he knows he has done something wrong and is about to get into trouble...), and it makes him look rather comical.

Somehow, pictures never seem to do things like this justice, but you can't tell me that these don't make you smile...
