Tooth fairy joke

Here is a cute one I came across recently..............
---------------------------------------------------------------------------------------------------------------
After losing another tooth, young-old Timmy became more curious about the mysterious tooth fairy.

Finally putting two and two together, he came right out and asked his mother, “Mom, are you the tooth fairy?”

Assuming he was old enough to hear the truth, she replied, “Yes Timmy, I am.”

Timmy seemed to take this news quite well.

But as he headed for the door, he slowly turned back toward his mother with a curious look on his face and said, “Wait a minute mom. How do you get into the other kids’ houses?”
