Whilst I think the Piss and Biscuits Challenge Cup is a good idea. I'd imagine some rather fundamental rule changes would be required including:
Cardigans being accepted under jersey wear
The use of incontinent pants as slider shorts
Toilets on the fifty
The front of a Zimmer frame is not a self check zone
Padded slider shorts may not be worn over plastic hip replacements (excessive padding)
Marshals will need to accept a certain amount of abuse from grumpy old gits
Wiping is no longer a 1:4:1 offence (lets face it only the over 35s wipe)
A player can be wiped down and put back in if he can convince the Marshall he forgot where he got shot (The Alzheimer Defence)
Excessive use of WD40 on chrome domes to encourage "glancers", and facilitate the "What hit? wipe" will be severely penalised.
Blue Fill is banned, as female ballers will attempt to disguise hits with Purple Rinse (either that or ban purple rinse)
Tesco carrier bag paint carriers are disposable kit
Mind you the series is but a mere pipe dream until JT invent the Spectra Bifocal lenses.........
