Fart Redwood?

So, Milo loves Lincoln Logs! Well, while we were getting ready this morning, Milo came running into our room all giggily and red in the face and said "Dad, the Lincoln Log Box says FART!" he went on to explain that "F" says ffff

"O" says AHHH "R" says rrrr and "T" says tah. FORT! not FART! so we had a little phonics lesson and he decided it would be funny to change the "O" to a "A" on the box. I have a feeling he will be letting many kids at school know that he can now spell fart.....we're so proud!
