A pun about Fender guitars is:
     
“A woman is accused of beating her husband half to death with his guitar collection. ‘First offender?’ asks the judge. ‘No,’ says the woman. ‘First a Gibson, then a Fender.”
 
The guitar joke has been cited in print since at least 2015, and has been printed on many images.
