A mixed herd of cattle were grazing on the open plain down in the panhandle. It's an unusual hot spring day with a cold front moving in. Mid afternoon a shelf cloud forms and straight line winds roar through the grazing bovines. The wind is strong enough that the cows get tipped over, but interestingly their male counterparts remain standing. After the storm passes, one of the yearling heifers moseys over to one of the bulls and asks why they didn't get knocked over. The reply...."We bulls wobble, but we don't fall down."
