Laverne & Shirley was an American television situation comedy that ran on ABC from January 26, 1976 to May 10, 1983. It starred Penny Marshall as Laverne De Fazio and Cindy Williams as Shirley Feeney, roommates who worked in a fictitious Milwaukee brewery called "Shotz Brewery."
The show was a spin-off from Happy Days, as the two lead characters were originally introduced on that series as acquaintances of Fonzie. Set in roughly the same time period as Happy Days, the Laverne & Shirley timeline started in approximately 1959, when the series began, through 1967, when the series ended.

When they bond later over drinks taken from LeVar Brown's liquor cabinet, Robert apologies, admitting that the puzzle would have taken him forever to finish as well.
