A bit of info: "Words are like toothpaste, once you get them out, you can't put them back in" made more sense back when toothpaste tubes were metal rather than plastic (so until the 1970s) and couldn't be easily 'unsqueezed' to get the toothpaste back in.
This is also why complaining about someone "squeezing the toothpaste from the middle of the tube" existed: crushing the metal toothpaste tube in the middle wasted the toothpaste in the lower half (something this troper was often guilty of as a kid!).
