If there’s a missed beat, it’s not the disks and cassettes but the chemicals that Andy’s using.

Andy looks like he’s lubing the chain – so oil? but then the bottle’s an off-colour
Muc-Off in the next panel. A perfectly good late 90s…spray chain cleaner.
At that time Muc-Off was just a product produced by X-Lite. It wasn’t until a decade
later that Muc-Off became so popular it became the company name and they sold
everything from lube to shampoo under that name too.

Of course, that – and the not pinkness – is just another subtle hint by Jon that there’s
something not quite right with this timeline. 😛
