How long would it take a grasshopper with a wooden leg to kick all the seeds out of a dill pickle 
well this question is somewhat of difficult one, because we have to assume things about hip flexor strength in this grasshopper. U see the power for the kick would be generated here unlike a normal leg in which the rectus femoris would extend the lower leg (that below the humerus) to aid the kick. So id assume that the grasshoppers hips would be to weak to do this task if wood weighs more then bone/muscle and interstitial fluid ect..
so i would have to say eternity thus creating a paradox because there is no end point in eternity yet me suggesting that he could do it if he had eternity makes no sense.
also was the grasshopper born with a congenital issue that resulted in the wooden leg? because if thats the case i bet his hips are even weaker, shit hes probably a sway back black hopper. However, if he injured it at work that would change the scenario because he would have normal strength (average, although he could be an outlier like king kamali and be super strong) thus making it a little easier.
then the pickle? is this soaked in anything? acetic acid would burn the grasshopper if given eternity, so that is a big issue.
too many variables here, i plead no contest.
