Gonna Have Myself a Great Day (the Colonoscopy Song)

As suggested/requested/feared - a song about my colonoscopy. Written yesterday/today. I just realized months later that I skipped the "bowel prep, bowel prep" bridge. Whoops.
Gonna Have Myself a Great Day (The Colonoscopy Song)

C F
I’m gonna have myself a great day
C F
I’m gonna have myself a good time
C F
Got to chug a lug a big ol’ jug of fizzy, salty PEG
C F
Just for little ol me and my colonoscopy
C F
1.875 ounces per minute of a drink you hate before you even begin it
G
Bowel prep, bowel prep,
F
Gonna put some pep in your step
G
Bowel prep, bowel prep
F
Gonna put some pep in your step
All that fizzy, fuzzy, funky fluid
Gonna hit the gastrointestinal system
and flow right through it
Two hours to force down a half-gallon of that jazz
Just to have it explode right out of yo azz
Get some rest, get some sleep, put up yo feet
Cuz in a couple of hours you get to repeat
8 more cups in two short hours of that vile and vomitous drink
Another half gallon that will have you gagging at the sink
Swallow, swallow, swallow what’s in the glass
Tighten, tighten, tighten up your ass
Run, run, run for the bathroom and
Squirt, squirt, squirt then do it all again

Polyethylene Glycol having itself a free-for-all
G F
Polyethylene Glycol making my colon its dance hall
G F
Polyethylene Glycol takes away all self-control
G F
Polyethylene Glycol spraying out my butthole
