Overheard this afternoon, during a messy lunch of milk and pb & j sandwiches:

boy #1:  (giggling)   "I dribble, so forth I am."

boy #2:  (correcting)  "I dribble, therefore I am."

boy #1:  "Oh, you too?"

Renee Descartes would be so proud.   He said his thoughts couldn't be separated from him, therefore, he exists. 

Apparently, peanut butter cannot be separated from young boys, either.  :)
