This is funny for two reasons. First, it reminds me of one time when my sister, Laura (age 6) asked my mother if she could get all her hair cut off. (My mother said no.)
The other reason this is funny is because my family has a tradition of drawing faces on appropriately-shaped produce. Butternut squash works particularly well. It gets especially funny when someone draws a face on the week's squash and signs his or her name!
I think the motivation for this probably came from Veggietales. Speaking of which, what's your favorite Veggietales song? Mine is "His Cheeseburger." These things are important, you know.
