What does it mean? (saw at a subway station)

looks like a "Never Gonna Give You Up" joke to me but i might be trippin [https://youtu.be/dQw4w9WgXcQ?t=41](https://youtu.be/dQw4w9WgXcQ?t=41)

Taskrabbit is advertising they offer mounting services, meaning they will hang pictures on your walls for you. Or take pictures down if that's what you want. The text of the ad is a parody of the Rick Astley song lyrics.

It’s a reference to the Rick Astley song Never Gonna Give You Up. It’s *very* well known among those of us who grew up on the internet, as it has been used for a variety of jokes. The lyrics have been swapped for words implying that the person reading the poster is not going to hang up the art they had intended to, so they should use the company being advertised (TaskRabbit) to have someone else do it for them. The swapped out words still work with the song’s melody.

It's alluding to a meme joke, a "Rick roll". People trick others into clicking a link to a specific pop song, "Never Gonna Give You Up", by Rick Astley. The lyrics to that include, "Never gonna give you up, Never gonna let you down". This is an adaptation of the meme. https://en.wikipedia.org/wiki/Rickrolling

I’m pretty sure that it’s a reference to Rick Astley’s “Never Gonna Give You Up” [The music video](https://youtu.be/dQw4w9WgXcQ?si=uWmvhH33mIjJFzQU)

It's a reference to the 1980s pop song "Never Gonna Give You Up" by Rick Astley (which has taken on a life of its own as the "rickroll" internet meme, where you prank someone by sending them the YouTube link to the music video).  The chorus lyrics ("never gonna give you up, never gonna let you down") are being parodied to refer to the poster being hung up. 

it's written in a way that sounds like the lyrics to this song: https://youtu.be/dQw4w9WgXcQ?si=kGRRtRwp82DJ4zqd *never gonna give you up, never gonna let you down* it's a well known song associated with the old school online meme, rick rolling: https://knowyourmeme.com/memes/rickroll actually, here's an even better link with a more detailed explanation: [link](https://youtu.be/dQw4w9WgXcQ?si=kGRRtRwp82DJ4zqd) ;)

It's a reference to the Rick Astley song "Never Give it up" and they apply it to signage. I don't really understand exactly what they are saying about it.

Taskrabbit is at company that provides services for light maintenance, like hanging pictures and window blinds or assembling that Ikea stuff for you. They are referencing the famous Rick Astley song for the purpose of making an amusing advertisement. (Taskrabbit doesn't employ the handypeople directly, but are a matching service for handypeople)

It's a "do not hang/attach signs" notice in the key of "never gonna give you up" by Rick Astley, better known as a rick roll

To add context to the existing answers, taskrabbit currently have an ad campaign that’s all about taking the lyrics of popular songs and changing them to refer to the types of household services you can book through taskrabbit!

One of a number of Taskrabbit adverts that are puns on popular song lyrics. Eg "I can see clearly now Lorraine has gone" for 'Lorraine' who offers window cleaning services Or "You are never ever putting that together" from 'Taylor' who is offering to put flatpack furniture together. To be fair, I was told by a guy who taught English as a foreign language that getting tabloid newspaper pun headlines was a very high level of English use. These are similar to such headlines.

now why no one rickrolled OP?

It's been almost two decades, but I finally get to post this link as a legitimate answer to something: https://youtu.be/dQw4w9WgXcQ But for a better explanation: https://knowyourmeme.com/memes/rickroll

the person who did that needs to be given 1000 papercuts and dipped in rubbing alcohol......

Is that… a Rick Roll? I think they’re using a Rick Roll, or like Never Gonna Give You Up the meme, to advertise stuff.
