While everyone has named comics that are definitely among the worst of Dobson, here are some I'd like to add-
His list comic where he basically says football fans are all homophobes while also secretly being gay.
ANYTHING with Talus. Because Talus literally makes an already bad comic even worse. Every time.
The very last comic he made before he rage quit (not counting Cabin's Rest) I think, where he directly compared the COVID-19 pandemic to the 9/11 attacks. He got A LOT of blowback for that and he threw a fit over it and denied that's what he was saying. Even though he clearly was, and I recall him even calling people "stupid" for thinking that was his point. Then failing to explain what his "real" point was. What a way to end his cartooning career. but it was also a very fitting end for him.
(Remember, this was when he was trying to blame Trump for Covid happening)
Honestly, those three comics you picked give a good overall example of why Dobson has the reputation he has, along with giving you an idea of the type of person he is.
