Owen is having a great time grabbing my lips, singing a song he learned at daycare. I had to Google it to find the words because I had no idea what he was doing (he's fixated on the 'creepy crawly' part):

Open, shut them, (open and close hands in front of you)
Open, shut them,
Give a little clap clap clap. (clap 3 times as you say “clap” )
Open, shut them, open, shut them,
Lay them in your lap lap lap. (fold hands in lap)

Creepy crawly, creepy crawly,
Right up to your chin chin chin. (fingers crawl up chest to chin)
Open up your little mouth, (open mouth)
But do not let them in in in. (quickly put hands behind back)
