Hero?

Obviously I'm not going to call here. What's the best play? Should I just shove it all in and hope I get one weak caller?

For some reason I can't get the converter to work right (not showing all 10 players) but basically there were 3 people who had already put out 55 in chips, plus myself and UTG who flat called the 15 chip min bet.
