We had never heard of LOL Cats/I can haz cheezeburger until we went to Boston some years ago to spend xmas with our kids and brand new grand son. Much oohing and awwing over the baby but then son showed us the LOL Cats site and we laughed until we couldn't stand looking at any more.
Later, they said they were just little miffed that we spent more time with LOL Cats than with our grandson. In our defense -- the baby was just a baby. Wonderful beyond words but, well, what do babies do? Once you've been spit up on and changed a diaper, that's pretty much it until after the nap, right?
