Make it something that is not common knowledge ....
For me:
I hold a Bachelors Degree in Business (Marketing Major), a diploma of Market Research, am Certified in Instructional Skills and am also a Qualified Quality System Auditor - 4 lots of letters after my name that I will NEVER use (because it is a wank).
Oh, that, and I had 6 professional fights as a heavyweight boxer way back when.
