Season 5, Episode 13
Steve connects with his ne'er-do-well paternal grandfather, whom Stan despises for many reasons, not the least of which is that he never taught him to ride a bike. (Others include his dad's criminal proclivities and, oh yes, abandoning the family.) Meanwhile, Hayley must find an internship for school credit quickly, so Roger hires her to tend his bar.
