JR made his first PB sandwich all by himself

What goes on in that little brain?

So the 'Blue Angel' Jets are in town for the air show. They repeatedly fly over head for a few days making quite the ruckus. Sid used to drop flat on the ground (like the way some people do when they hear gun shots). Not anymore, this is his third year of the air show- he's so grown up now... but this is the first year JR is old enough to react. When he hears the jets overhead he starts shaking like he's seizing.

Today JR and I took Rosco for a walk and the jets flew by. He had his usual reaction, but after the noise was finished, JR started exclaiming, "volcano! volcano!" I thought he was so smart. That loud thundering noise did sound similar to what a volcano would sound like. Then I thought, how does he know what a volcano would sound like in the first place?
