Brian had been at the Royal's Game with friends (it was Zubaz night, Royal's vs. Detroit Tigers), Mackenzie had been out on the town with girlfriends. On the patio with a group of friends, Brian, wearing his Zubaz headband (for those of you who are unfamiliar, Zubaz night happens once a year and includes give-aways of scrubs and headbands patterned with blue tiger stripes - real flattering) approached Mackenzie at the bar.
A few Boulevard Wheats later - exchange of phone numbers - a goodnight kiss
...and the rest is history.
