Come on now Derg. I really have to laugh at that. If you have a gap just adjust the damn dates so there aren't gaps, not rocket science. I wouldn't remotely consider putting "two weeks living on the couch at so and so's house" on the SF-86 for a security clearance so I sure as hell wouldn't put it on a job application. Then again, I'm not applying so I guess YMMV...
Usually its much larger gaps. Don't shoot the messenger, esé!
