After the usual greetings, the earth mans asks the chap from Mars if they have shares & stock markets up in Mars, Yes replies the Mars chap just like you fellas down here, then the earth woman asks what about sex, yes the same as you earth people he says, well how about we swap partners tonight and check it out. So they all agreed and that night the guy from Mars gets undressed & the earth woman see's this tiny wee pecker & laughs, Bloody hell you wont do much with that little thing she laughs, no problem says the Mars man & he startspunching his nose & his willy gets longer & longer, not bad says the earth woman but it's still to skinny, no problem says the Mars man & he starts tapping his cheek and fatter & fatter his willy gets, well the size puts a smile on the earth woman & away they go. The next morning she meets her husband & he ask her how lastnight went, Wonderful she says how about you? Bloody strange them Mars woman all night she puched my nose & slapped my face.
