Tiggy
Thanks to the posters here, I am better educated about this.
It seems to me that the caption can be interpreted positively, lampooning an infantile patriachy, or it could be partly directed at the Lady, objectifying her because of her "support" of the porn industry.
Given the potential for negative ambiguity, isn't this a poor choice of caption? I have respect for PE and their role (and humour) but this falls below the standard I expect from them (them being nearly all posh blokes).
