I think "putting my hands in my pockets" is only slightly more believable than Wayne Hennessy saying he made a Hitler salute - including comedy moustache - because:
"I waved and shouted at the person taking the picture to get on with it" and "put my hand over my mouth to make the sound carry"
Mind you, one cannot discount immense stupidity and unlikely explanations with regards to football matters, given the FA panel said that under cross-examination, they were convinced that he genuinely didn't know what a Nazi salute was (despite doing one):
"In fact, when cross-examined about this Mr Hennessey displayed a very considerable - one might even say lamentable - degree of ignorance about anything to do with Hitler, Fascism and the Nazi regime."
