I used to work at an engineering firm and one day I saw one of the engineers leave at like 2pm on a Wednesday and he was like, "Bye, see you next week!" He had been busting his ass to finish a project and already hit his 40hrs for the week.
I was a temp at the time but needless to say, I jumped at the chance when they offered me a real job.
Marcus Veltri (piano) and Rob Landes (violin) for anyone who's interested.
I'd also like to recommend Frank Tedesco for a similar kind of shtick but is funnier imo.
