I'm the same way with my boys. At least once a day I sneak up on them and give them a "CRUUSSHING!" I basically impersonate a Russian professional wrestler from the 1980's. "Zangief will crush you little boy! Bah hahahahahah!" (I came up with Zangief from Street Fighter.) I'll flip them on their heads and tickle like crazy. It busts us all up every time. I'll even sing them a lullaby I made up called "Rock-a-by-CRUSHING", where you sing the song normally, cradling the kid, and at the "when the bough breaks, the cradle will fall" part I go into "YOU WILL BE CRUSHED! BWAHAHAHAHAH!" and then lots of tickles. At the grocery store last Christmas I was probably singing "Crushing bones, crushing bones, crushing little bones!" to the tune of Jingle Bells a little too loudly. But they liked it. Man, I'm going to miss it when they get a little older and realize I'm just some lame and embarrassing dad.
