Cash Machine Jokes

Okay, so listen up. The joke is that the word "ATM" is an abbreviation for "Automated Teller Machine", which is another name for a cash machine. But "ATM" is also used as an abbreviation for "at the moment." So, the joke is a pun, because they are using the same three letters in two different ways. You probably didn't know what a pun was, because you're kind of a dum-dum, but a pun is using a word in a funny way where it has two different meanings.
