par for the course

so, there is this guy at work who tells stories of how he has done this and that and everything else during his tenure at this place of employment and he's always "Hey, look at me. I'm the cat's meow" and such, and he's going on and on about something unbelievable, I just basically ignore him, I'm just nodding and stuff just so I won't be rude when his story finally ends, one of my co-workers comes over to me. This co-worker is a mother of two and a grandmother to three and she says to me "Years ago I was in an argument with him about birthing a child. He thought he knew more bout it than me"
