(Btw, am I the only one here that still occasionally laughs inappropriately when nervous or when someone's switch gets flipped?! Happened to me a ton as a kid, too...I was shy and could never hold back giggles when in trouble or nervous; don't know why.)
My almost 4yo does this. As well as trying hard to distract me or change the subject when I am being serious with him. I was the same way (and still am) with my parents.
