The sentence "One day my dad and his brother stop me if you have heard this story started out on what they thought an uneventful drive to work" has several punctuation errors. Here's a breakdown and how to fix it:

1. Comma after "brother": You need a comma after "brother" to separate the introductory phrase "One day my dad and his brother" from the rest of the sentence.

2. Period after "story": The phrase "stop me if you have heard this story" should be separated from the rest of the sentence. It's an interjection, so a period after "story" would be appropriate.

3. Comma after "story": You also need a comma after "story" to set off the interjection.

4. Capital letter for "started": The word "started" should be capitalized because it begins a new sentence.

5. Question mark at the end: The sentence is a question, so it needs a question mark at the end.

Corrected Sentence:

One day my dad and his brother, stop me if you have heard this story. Started out on what they thought an uneventful drive to work?
