dad
Explanation
This comic is a time-travel joke. A child finds his father, whom he believed was shipwrecked and killed, only to discover that his dad is on a boat full of naked women cruising the seven seas. The father sheepishly says "Honestly, I did not anticipate this scenario."
The caption at the bottom reads "This is the main risk of traveling back in time to stop a parent's death." The joke is that the child traveled back in time to save his father from dying in a shipwreck, but by preventing the disaster, he inadvertently allowed his father to continue living a hedonistic lifestyle that the family never knew about. The comic plays on the classic time-travel trope of unintended consequences -- sometimes the past is better left alone, not because of paradoxes, but because you might discover uncomfortable truths about your parents.
