For a while now E has been trying to figure out what adults think is funny. She is always asking us why we are laughing or what is funny. And she has this loud fake laugh that she uses to laugh along with us (complete with 5 sec delay) to show that she too is part of the gang. Remember when DATA was trying to understand humor?
Z is also getting in on the ha ha. Her new word of the week is "funny". Sometimes when she uses it I understand what she means and sometimes her sense of funny and mine are not in the same stratosphere.
