Last time, I recall one candidate affectionately known as
"slipper man" who didn't go around canvassing for votes during the
elections.
Think he got a decent amount of votes though he did not win.
Let me try to google and see what I can find about him.

You still mention this wasted slipper man?
This slipper man was DPP member, who happened to be involved in
the murder case (Son's PRC Wife kill dunno who and get 16 years in
jail).
What happened is this father-son (So dun accuse PAP, as
opposition also got father son / daughter as well), father went to
many cornered fight in CCK, worse than some independents who
managed to get less than 2% (Less than 500) of the votes while this
son went into Kampong Glam in 1997 and earned 29.7% of the
votes.
Sad to say, by 2001, this father went to MacPherson SMC and got
16.8% of the votes but his son go to Ayer Rajah (At Teban) SMC and
got 12% of the votes, which happened to his (son)'s turn to lost
the deposit (Lost deposit = Earned less than 12.5% of the
votes)
By 2006, his son went to 10Penis with SDA and lost with 31% of
the votes, his father, did not stand to become a candidate.
