Dad Joke About 'Look After You' Pun

This is a 4-panel digital comic. In the first panel, a person in a red shirt smiles and asks a person in a blue shirt, who is using a seaside observation telescope, 'CAN I LOOK AFTER YOU?'. In the second panel, the blue-shirted person answers 'NO' without looking away from the telescope. In the third panel, the red-shirted person looks confused and asks 'WHY NOT?'. In the final panel, the blue-shirted person turns to smile at them and replies 'I ALREADY HAVE A DAD'. The joke relies on a pun: 'look after you' can both mean taking a turn looking through the telescope after the current user, and acting as a caregiver/guardian for someone, which is a role typically associated with a dad, making it a classic dad joke.

This original comic is created by the artist Twonks, as indicated by the watermark at the top left of the image. It was shared as a meme on the Reddit r/Meme subreddit, sourced via RSS, and is noted as qualifying as a dad joke in its original post title.
