Here are a few options for song parodies about Luke and weed, based on different popular tracks:
Option 1: To the tune of "Thinking Out Loud" by Ed Sheeran
(Since your prompt mentioned "thinking i out song")
"When your eyes don't work like they used to before
And I’m passing the joint to your hand
Will your lungs still remember the taste of the herb?
Will your mind still be in wonderland?
Cause Luke, your soul could never grow old, it’s evergreen
Your stash is the loudest that I’ve ever seen
I’m thinking ‘bout how people fall in love with the bud
Maybe it’s part of a plan
I’ll just keep on rolling with you every day
Luke, take a hit while you can."
Option 2: To the tune of "Starboy" by The Weeknd
"Look what you've done
Luke's got the lighter and he’s having some fun
Safe in the clouds and he’s on the run
Pounds of the green, yeah he’s got a ton
He’s a cloud-boy."
Option 3: To the tune of "Bad Habits" by Ed Sheeran
"Every time you come around, Luke, you know I can’t say no
Every time the sun goes down, you let the bonfire glow
And I let the rolling papers take control of me
Looking for a snack now, yeah, we’re hungry as can be."
