A Cluster of Limericks

The Insomniac An insomniac of the Bahamas, Went to the zoo in pyjamas; The counting of sheep, Had not helped him sleep, So he'd got a prescription for llamas. A sailor and a scientist, a bishop and a botanist, a tourist and a tarantula; all these and more can be found in their own little limerick. There are 103 limericks in this collection, and 102 of them are not about violins.
