At the Tabard, said Harry, one day,
In a friendly and jocular way,
We're in no hurry to reach Canterbury,
So let's have some tales on the way . . .

The halls of your balls
Have some very strange walls,
As Sertoli found out,
None too soon,
So if one should ask,
The distance is vas,
When you go from 'tocyte
To 'tozoon . . .
