Bid Central allows you to add aphorisms to the F/A briefing form. If you want aphorisims on the form, you can turn this feature on under "Preferences".... "User Profile".... "General Preferences". Here's how the aphorisms appear on the F/A briefing form.
You can view the Aphorism Screen by selecting "Reports"...."Flight Attendant Briefing Form for all Segments"..."Aphorism Display and Entry Screen". This is what that screen looks like.
Use the [+] and [-] buttons to cycle through the pre-loaded aphorisms.
