sideshow bob jumped into the lake with all his clothes on i dont know what he was thinking.

Explanation:

The original sentence has two independent clauses ("Sideshow Bob jumped into the lake with all his clothes on" and "I don't know what he was thinking") that need to be separated. A semicolon or a period can be used, but given the context, a semicolon is appropriate to show a close relationship between the two thoughts. Also, check capitalization (already correct here). So the corrected sentence is: "Sideshow Bob jumped into the lake with all his clothes on; I don't know what he was thinking."

Answer:

Sideshow Bob jumped into the lake with all his clothes on; I don't know what he was thinking.
