My favorite are the retards that list them as credentials behind their name. like: Joe Shmoe EMT-P, ACLS, PALS, ITLS, NRP, AMLS, GEMS. (you know who you are)
That made me crack up! The joke is, most places require you to have most of these certs just to apply. It's not like you're going above and beyond by getting these, or giving yourself an edge in hiring, or anything.
