Alien reproduction
Scientists studying a pair of visiting aliens ask how they
reproduce. The male alien says "Here, will show you" and
proceeds to intertwine his antennae with those of the female
for 15 seconds afterwhich a sack beigns to expand on the
feamle's back. 60 seconds later the sack breaks open and a
minature alien pops out. "That's how it's done says the male
alein. How do you earthlings reproduce?" The male
scientist eyes his attractive female assistant and says
"Shall we demonstrate?" The female assistant feeling
somewhat frisky replies "In the interest of scientific
interchange, of course" and the two proceed to engage in 30
minutes of fantastic sex. "There", says the scientist
aftterwords, "that's how we earthlings reproduce!" Fine
replies the alien, "but where's your offspring?" "Oh, our
gestation period is 9 months" says the scientist. "9
months?" questions the alien, "but if you have to wait 9
months, why were you in such a hurry at the end?"
