American toilet humour

A couple of comments about this ad. First, wouldn't it be better to have the guy single and desperate, rather than having his (presumed) girlfriend or wife turn up at the end? (If it was in an apartment building, wouldn't it have been funnier to have the plumber herself seeing him doing this?)

Secondly, is there some issue about Americans needing stronger flushing power than the rest of the world? It just seems a bit of an odd feature to be promoting in a toilet.
