Lucky: Silly heroine name

Like the legend of the Chicken
The plot could only thicken
What keeps the planet tickin’
Is the Underdog I’m pickin’

She’s got a limb that turns into a bomb
That’s kind of dumb but I’ll take her to prom

She blows up in self defense
It makes our dates a bit tense
Although her name makes no sense
I’m on this show to Get Lucky
