While out flying I was told that I was #2 for the runway behind a Falcon and the controller asked me to advise them when I have in sight -- and then follow them in.
Then I thought about it. Over the past 2 months I've probably been asked a dozen times to follow a challenger, a lear, a citation, a falcon, a gulfstream, a hawker,... and every time I've acknowledged it and then promptly start scanning for anything that looks like a jet in the area they advised it to be and just follow that jet in.
But then it struck me... I actually have absolutely no idea what the difference between any of those planes are except that the lear/hawker tend to be small while the gulfstream and falcon tend to be big. I could have been following the wrong jet every single time and I wouldn't have known it. Anywho, random thought that hit me and caused me to google all those jets to try and commit some to memory lol. The good news is I've never had an issue following the wrong one.
Now, ask me to follow any single engine piston plane and I'll be able to identify it almost every time!
