Just goofing off with formatted serial output (ANSI)
Remember Ansi? :)

Code:
int lbuttonPin = 17; // Left Button, on analog 3,
int mbuttonPin = 18; // Middle Button, on analog 4
int rbuttonPin = 19; // Right Button, on analog 5
int lbuttonBit = 8; // pin17 is a bitmask 8 on port C
int mbuttonBit = 16; // pin18 is a bitmask 16 on port C
int rbuttonBit = 32; // pin19 is a bitmask 32 on port C
//pretend we start with upressed buttons
int buttonpins = lbuttonBit + mbuttonBit + rbuttonBit;
//attach the interrupt
ISR( PCINT1_vect ){
buttonpins &= PINC;//bypassing digitalRead for interrupt performance
}
void setup() {
Serial.begin(9600);
pinMode( lbuttonPin, INPUT );
pinMode( mbuttonPin, INPUT );
pinMode( rbuttonPin, INPUT );
//"turn on" the internal pullup resistors
digitalWrite( lbuttonPin, HIGH);
digitalWrite( mbuttonPin, HIGH);
digitalWrite( rbuttonPin, HIGH);
//low level interrupt enable stuff
PCICR |= (1 << PCIE1);
PCMSK1 |= (1 << PCINT11);
PCMSK1 |= (1 << PCINT12);

}
