Giant inflatable penises

Good morning readers.  Some have asked how Mycroft can be so sure that the Hen parties he observed were carrying inflatable penises.  The thrust of the question (boom boom) seemed to be that it was possible the giant replica penises were in fact not inflatable, but solid or indeed a hard non inflatable shell.  At first I thought my readers had spent way too long thinking about this and was inclined to insist that the Hen night props were clearly inflatable.  However, I soon realised that the matter needed to be addressed.

I suspect that the considerations for Hen night props are:
1. The item must be able to be transported
2. The item must be 'shocking'
3. The item must relate in some way to penises
4. The item must be noticeable

All the above considerations dictate that the ideal Hen night prop must be large (in order to be noticed, and to shock) yet light in weight in order to permit mobility.  As the item must also relate to penises in some way, a large yet mobile (or portable) fake penis is thus the item of choice.  An item with a hard shell which would not collapse would be expensive to manufacture, package, transport and store in a retail supply chain.  A solid object would be impossibly heavy as well.  So thus we conclude that the giant penises were inflatable.

Mycroft now stands by for questions regarding whether a proper market survey has been done.  Perhaps next week.
