Three School Boys

[Rondy]

Three young school boys are smoking behind the bike shed. The first lad says: "My Dad can blow smoke through his nose."
The second lad says: "My Dad can blow smoke through his ears."
Not to be outdone the third lad says: "That's nothing, my Dad can blow smoke from his ***...and I've seen the nicotine stains on his pants to prove it."
