Farting and farting jokes always crack me up and always will.
I have a 5 year old grandson and so far Nana Pam has bought him a remote control fartbox and a tub of that sticky stuff in a pot that Billy Connelly was talking about in that clip you posted.
I don't fart in front of other people but I always fart in front of my Grandson and do the usual "Was that you Jack? Or was it the fart fairy?"
Jack comes and stays with me often and we make play doh and play cards and I read him stories....
And he doesn't ever ask about his Mums I phone. He is forever playing on it when he is with her. She calls her I phone her 'babysitter'.
Grandchildren are such FUN....
If you can't fart in front of your own grandchildren who can you fart in front of?
