Explain this crossword clue and answer

Normally I can get the relation between tricky or punny crossword clues and answers, but I’m a bit perplexed about the relation between clue: 2 letters, and answer: ABC. If the clue were: 3 letters, or the answer were TWO (or even an anagram thereof), I’d be OK. Help me get this one.

Look at your cell phone or telephone.

LG? :confused:

:dubious: The keypad to dial a phone number - #2 button is ABC.

Don’t go giving me the ole stink eye. That there was a joke.
