For example, Complains Clerk has "Whenever you roll a 1, create a 1/1 white Clown Robot artifact creature token." If you choose that ability, you ignore everything up to the first comma, ending up with "Create a 1/1 white Clown Robot artifact creature token."

If you choose such an ability with Trigger Happy, you ignore the trigger event, and the ability will go on the stack even if the intervening if condition is not fulfilled, but the ability will still check the intervening if condition as the ability tries to resolve
