Three little boys had been to the zoo on a field trip and were discussing
which animal was the meanest.
The first selected a Tiger because the Tiger has sharp claws and large
teeth.
The second selected an Aligator because it had more teeth than a Tiger and
it could drag you into the water and drown you.
The third child selected the Aliger, which her explained, had a Tiger’s
head on one end and an Aligator’s head on the other which made him twice
as mean.
“Wait”, said the first little boy, “If he has a Tiger head on one end and
an Aligator head on the other, how does he take a shit?”
“He doesn’t”, said the third little boy, “that’s what makes him so
mean!”
