- "Before this product, I was a fat, lazy, stupid, unwashed schlub who sat on his couch all day eating potato chips and playing Xbox. Now, I'm still a fat, lazy, stupid, unwashed schlub who sits on his couch all day eating potato chips and playing Xbox... but with a cool new hat! Thankyou, This Product*!"
- Douglas Adams' The Meaning of Liff lampshades this, defining the word 'Liff' as any product which does not live up to its claims, and specifically any book with the words 'This Will Change Your Life!' on the cover. The book itself, of course, had a sticker stating just that.
- The newer edition, The Deeper Meaning of Liff, dropped this gag and redefined the word as "a common object or experience for which no word yet exists," arguably preserving the self-reference.
- Spoofed brilliantly in a commercial for Bubblicious Bursts, which featured oversized bubbles allegedly blown using Bubblicious Burst changing the lives of everyone around them. The announcer billed it as "great for parties!", "fun with cats!" (featuring an uninterested cat standing next to goldfish swimming in the bubble), and even good for helping Dad around the house. "Just ask Superstar Lebron James!" was the next-to-final remark made in the commercial (featuring an image of Lebron blowing a bubble of generic gum with a superimposed thumbs-up over him). The final remark was a large group of people yelling "Thanks, Bubblicious Bursts!" for no particular reason. (Of course, the company included a disclaimer at the end, stating that "Bubblicious Bursts is great for blowing bubbles, and nothing else".)
- The The Kids in the Hall movie Brain Candy features this testimonial endorsing the wonder drug Gleemonex:
- "I used to live on the street. Had cardboard bum from sleeping on cardboard. Then Jesus— I mean Dr. Cooper gave me his drug. Now I'm more productive. I'm a security guard. With a gun."
- One of Bernard from Black Books many, many efforts to avoid customers in the store involved him picking up the book closest to the door and handing it to the potential customer, saying "You'll laugh, you'll cry, it'll change your life".
- "If You Buy This Record (Your Life Will Be Better)", a song by The Tamperer, as one might guess from the title, parodies this trope.
- The satellite television service DirecTV is now promoting itself using the slogan "Get DirecTV today: it'll change your life."
- ThisTom Waits song will Change Your Life.
- skip to 2:34 to hear the trope name and possibly turn into a 9 year old hindu boy.
- A radio Public Service Announcement for British weapon enforcement campaign Trident parodies this trope grimly:
Narrator: There's a guy I know. Got himself a gun. Said it would change his life.He was right - it completely changed his life.He's dead.
