This is where I remember seeing a similar image:
But it is quite possibly from something else and is being referenced in that theme song. It doesn't seem to be in the theme song for the original (unless there were multiple versions but the original looks to all be live action).
Al already mentioned in the discription
It's a copy of images I see in somewhere😁
So I'm guessing the odd couple intro wasn't the somewhere you saw it? Either way I'm proud that I managed to remember where I had seen a similar image after it being quite a while since I saw the odd couple reboot, even if it unfortunately didn't help you work out where you saw a similar image
