Riding Bikes

We spent some time riding bikes a few days ago outside because it was so nice.  I could tell the boys weren't used to riding on their seats, they got tired fast, etc.  When we were putting the bikes away, Jonah said, "Mom, my intestines HURT!"  I stared at him....wondering....intestines?  Really?  Then it dawned on me...."Ohhhhhh!  You mean 'testicles'?"  He blushed and said, "oh,..yeah."  I thought it was sooooo cute.  Last time he called the lymph nodes in his neck (cervical lymph nodes Paul tells me, but I didn't want to say cervical lest anyone think I was meaning a different area!)--'intestines' by accident.  He just can't get the right location with the right word!
