Several of them are lyrics from Mary Chapin Carpenter

i bought a pack of camels, a burrito and a Barq's

---I bought A pack of Camel cigarettes, a taco and a bottle of Barq's.

My eyes just about popped out of my head

---My eyes are about to pop out of my head. Surprised)

made a beeline for the park

---go straight to the park

trying to catch my eye

--- Trying to get my attention

i'd bought the house a double

---Give everyone here a double

(from a lyric , refers to a good mood or an unexpected fortune, the House is usually a restaurant or bar)

the stars are stacked against you

---too bad luck

(The original meaning is probably that according to the astrology, the arrangement of the stars is not good for you, you will be unlucky)

tumble out of my rack

---from my Roll out of the shelf

(This has no context, I don’t know what it refers to)

my daily dose of destiny under my sign

---My day Fortune

(from the daily horoscopes in some newspapers and magazines, my sign is my horoscope)

the stars might lie but the numbers never do

---Numbers don't lie

(The first half of the sentence is just for comparison, it may be inaccurate to look at the stars, the key is the second half, it depends on the facts)
