hee haw

i picked up the kids from school today.  in the car, john and i talked a little about school.  then he turns to me and says, "mommy, what says, 'hee haw', has one tail and four legs."  i say, i know, a donkey.  he giggles.  then he says, "mommy, what has two tails, eight legs and says 'hee haw'?"  i think to myself, really is it that obvious? or is it a trick?  i say, i don't know john what?  he laughs and says, "two donkeys." 

i say to him, when you were little and learning the noises animals make, we would ask you what a donkey says.  and you would put your hands on your head like donkey ears and say "hee haw."
