My word of advice..Try not to be a smart ass, but if you must, at least interject some humor in it..

As I recall being asked by a foreman some 30 odd years ago, when I arrived to the job site about 20 minutes late...

"What time do you think we go to work around here?"

Shrugged my shoulders and said..
"I don't know...You guys are always working when I get here"..

He laughed and sent me to the rail pile..LOL..

It Don't mean a thing if it aint got that swing.
