I listen to far too many podcasts, these are my favourites:
Judge John Hodgman - lighthearted domestic disputes
Beef & Dairy Network Podcast - comedy series about the beef & dairy community (you have to listen to this one from the start, the story grows; it's very silly)
My Mate Bought A Toaster - a different comedian each week goes through their Amazon purchase history
Scam Goddess - true crime, but about scams only. The host is hilarious, and each episode she tells a different comedian-type person about a famous scam (the heiress and the McDonald's monopoly ones are fantastic).
Stuff You Should Know - My overall favourite podcast. Over a thousand episodes, the hosts just explain a different subject each episode and they cover everything; science, crime, culture, history. You can just scroll until you find something that interests you.
And if you have favourite TV series', there'll probably be a podcast about it. There are official ones for things like Better Call Saul and The Good Place, and fan-made ones for things like Frasier.
