Everything in North America is 'oversized' including our plumbing to handle our oversized dung...

Avtually I was referring to the size of the bowl. The UK Crapper (yes that is an appropriate word since that was one of the original brands) has a far smaller water table than a US model. Obviously this has display/measurement implications if you see what I mean. The UK version also has a far more vigorous flush action and a much larger outlet. If anything I'd say the US version is less able to cater for the sort of vigorous effort described by Grady. At this point I could share experiences from a hotel in Minnesota where I stayed for some months, but as there is a lady present I won't. ;-)
