b/c,b/c,b/c

Has anybody ever used this line?

bet/call,bet/call,bet/call.

I used this line today and felt like a muppet for doing it.
I'm just wondering if anybody can think of a situation where this is correct.

This was mine.

Sorry, I'm at work, I don't have the HH. It went something like this.

Hero is BB with K[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/spade.gif[/img]
3 limpers, SB completes, <font color="red">Hero raises</font>, all call.

Flop: (10sb) <font color="blue">(5 players)</font>
Q[img]/images/graemlins/club.gif[/img], 9[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/club.gif[/img]
sb checks, <font color="red">Hero bets</font>,<font color="gray"> fold</font>, MP calls, <font color="red">CO raises</font>,<font color="gray"> SB folds</font>, Hero calls, MP calls.

Turn (8BB) <font color="blue">(3players)</font>

<font color="red">Hero bets</font>,<font color="gray"> MP folds</font>, <font color="red">CO raises</font>, Hero calls.

River (12BB) <font color="blue"> (2players)</font>

<font color="red">Hero bets</font>, <font color="red">CO raises,</font> Hero calls.

Final Pot (16BB)

Should I just 3bet the flop or is the SNG a good idea?
