What's the last thing that made you laugh out loud completely alone

[Quiet Glacier]

A video of a cat getting spooked by a cucumber, watched it at eleven at night by myself and genuinely woke my partner up laughing, still can't fully explain why it hit that hard

There's something specifically funny about laughing alone versus laughing in a group, no social pressure or performance, just genuinely caught off guard by something

Curious what people's most recent version of this actually was, the thing that got a real laugh with literally nobody around to see or hear it
