I talk about this in my presentation, and it's time to write about it.
I've seen people try to be funny with sarcasm, irony, or jokes on their resumes. I've seen them try it in blog posts, and even in interviews. Surprisingly, the live attempts work the best because I usually have some context, some inflection and body language.
Trying to write humorously is hard. Very hard. Even when it works, it's often because the reader is being led down a certain path that provides them with a framework for the joke.
Most of you aren't funny at all. On your resume, when I'm in a frame of mind to evaluate your talents, it really doesn't work. You might get a smile or chuckle, but most likely I'll view you as not serious, and a bit of a crackpot. Most likely I'll just chuck your resume.
The one guy that tried to be funny, ended up really strange, and got an interview? We interviewed him only because we were wondering who would put that on a resume. We never had any intention of hiring him. I know, that was wrong and mean, but it happens.
Don't be funny. If you think you are, go to the local comedy club on Tuesday or Wednesday night for an open mike.
Be professional when you want a job.
