A mother goes to Doctor about the size of her sons genitals.
"Doctor i am really worried about the size of James's penis, its tiny."
"Don't worry when he hits puberty he will be fine."
"But Doctor its so small, how will he be able to keep a girlfriend happy when he's older?."
Not seeing how else to get rid of her, he decides to make something up.
"OK, this is an old wive's tale but apparently if you give him loads of toast it should start to get bigger in no time."
"Thank you Doctor, thank you"
The next day little James come down the stairs to see a whole loaf has been toasted and is sitting piled up on the kitchen table.
"Mummy is that all for me?"
"No son, just the top slice, the rest is for your dad."
