When the main character of a TV show is the uncle/grandpa/brother/dad of every person in the world (including, presumably, himself), you have to expect time travel sooner or later. In this case, I think the first time travel was when a future Uncle Grandpa delivered a future pizza. The only time traveling that I’ve seen, however, involved the wayward pants that Christopher Columbus refused to return
If I don’t get my pants back by the end of the day, ’m calling the time police.
