Years ago I was reviewing resumes with my boss. He handed me one and asked for my input.

The email address ended in 420. I told my boss that either they and Hitler had something in common or they probably won’t pass a drug test. My boss asked for an explanation and I pointed out the email to him. He just took the resume and binned it.

So yeah, don’t put 420 in your email even if you share a birthday with Hitler.
