If the fiance' is hot add these;
6a) When he's in middle of lap dance or in other room with said whore call fiance' and tell her she needs to come over right away.
6b) After she enters and gets all pissed off, console her and tell her what a pig she's really marrying. Also tell her she needs to get revenge, a sort of tit for tat thing and volunteer
6c) Bang her in adjacent room while he's passed out then kick her to curb and call her slut.
6d) When friend wakes up tell him he's totally busted because fiance found out about whores.
6e) Find new friend
