Meanwhile, Brian tries to score on a date with a new friend, Denise (guest voice Jessica Stroup), but ends up striking out. Instead of calling it quits on love, he decides to enlist Quagmire’s help, but things get nasty when they start to compete for the affections of each other’s old flames, Cheryl Tiegs (guest-voicing as herself) and Jillian (guest voice Drew Barrymore).
