Keelan Harvick shows off mad dancing skills on a plane

We already knew young Keelan Harvick -- that's Kevin and DeLana's 3-year-old son -- was an inquisitive little guy.

That was most recently made evident from a couple well-thought-out questions he asked his mom.

In addition to clearly being both curious and intelligent, Keelan, it appears, also knows how to break it down.
