what you say when you are late in office ?

haha.. call me silly.. but on the course of my first job, coming in late became something regular for me. my schedule was 8am-5pm. and normally, i get to office at around 10am, and ironically, my boss comes in ahead of me. so, when i get in, nobody really asks anymore. so i just blurt out, "hey guys, whats up?". hehehe.. and the company can't let me go because i'm one of those who rake in money for the company.
