20. Saying "Lets have a threesome. You, me and your sister" to your 
 wife/girlfriend would get the response, "What a great idea!"  
 I don't recall that being the exact answer to this suggestion on Saturday night :P 
 The next question was then pointed at sister and bloke 'well how about we swap for a bit then?' ..... you gotta love him for trying dontcha!!  
 Oh the joy of having a sister who is better looking, slimmer and has bigger boobs
