You can't beat the shit out!!

A friend with managerial background once complained that he can't withstand people making weird noise with their burps right after dinner. And that he feels like beating the shit out of them. To this my immediate and involuntary response was that "Technically speaking, you can't beat the shit out of the person who had just had food. You would more likely be immediately successful in beating the vomit out of him. :P Upon my remark he tried to justify by stating the implied meaning of his previous statement.
The third guy, a layman (in  other words a genius), in our company got seriously agitated with the nature of this discourse, and screamed "Shut it, you geeks!!". And laughter took over !!!
