This one's a goodie...
There's a Priest and two Hirakrishna's fishing on the lake...
the one Hirakrishna says to the others "we are out of worms"
so he walks across the water to shore to get worms...
the other Hirakrishna says to the Priest "I forgot to tell him that we are out of wine"
so he walks across the water to shore to get some wine...
the priest is sits there thinking to himself if their god lets them walk across the water why not his god allow him to walk across the water...
so the priest tries to walk across the water and falls into the water...
meanwhile the two Hirakrishna's are on the shore asking eachother if they should have told the Priest where the rocks were...
