Noah's newest ploy

Let's just say my 3.5 year-old is too smart for his own good.  Now, if he doesn't want to go to bed at night, he tells us his "tummy hurts" or he's "sick in his tummy." Then he runs into the bathroom, leans over the toilet, and gives the best performance of spitting and groaning to feign throwing up.  Isn't it every parents dream to watch their kid stick his head in the toilet for no reason?  Awesome.
