A recall would have been more in the April Fools spirit. However, bitogers take their oil seriously, and if one did an oil change to get the "bad" oil out before you let them in on the joke, oh boy!!!
My mom used to get me almost every year (may she rest in peace, at least I can now on April 1st). Even when she was in her eighties she was sharp as a tack and get me ocasionally. One year she called me up to say she getting married but my sisters were calling her a tramp for re-marrying less than ten years after my dad died. I called one up and yelled at her until I realized she was laughing hysterically. My mom had tried it on her first. Then they decided to call me and add the twist of with my sisters.
I still hear that one recounted at family gatherings. Heck at MY funeral somebody will get up and tell that story.
