Dirty forwarded emails

My buddy Andy forwards me X-rated emails all the time.  I really enjoy some of the videos and the wide variety of material that I recieve.  The Christmas breast wishes card was actually compliments of Andy and his buddy.  I just really need to be aware of where my children are when I open his mail.  I had a very close call the other day when I opened the banana smoothie video!  I do not think my wife would like hearing from our 5 and 6 year old daughters that daddy is watching a lady on the computer shoving a banana up her pee hole and butt hole at the same time!!!!!!
