This reminds me of an old law office joke:
An articled clerk left the office to have a haircut.
On his return he was met by the senior partner who noticed both that the clerk's hair had been cut and that it was during office hours.
Senior partner: "Have you just had a haircut?"
Articled clerk: "Yes."
Senior partner: "During office hours?"
Articled clerk: "Well, it grew during office hours."
Senior partner: " Not all of it!"
Articled clerk: "Well, I didn't have all that cut off!"
Needless to say, in the fullness of time, the articled clerk became a solicitor and then a partner in the firm and eventually the senior partner.
