I was thinking the other day about the expression, "drop a dime on him"; meaning to make a phone call at a payphone to report someone to authorities.
Since payphones are almost extinct and they no longer cost only a dime the origin of this phrase is lost in antiquity.
How many others can you name?
I will begin the list with these:
In the groove
Dial the phone
Give me a ring (few phones ring anymore; most no longer have bells)
