I remember Barney having different voices, but I didn’t know the details until I looked it up.
- Mel Blanc was the primary voice actor for Barney, though the way he did Barney’s voice changed over the course of Season 1, initially using a higher-pitched New Jersey accent, but switching to a deeper, less smart-alec-y voice later on.
- When Blanc was recovering from a near-fatal car crash, Daws Butler stepped into the role for several episodes in Season 2.
- Blanc returned to the role once he recovered, but his Barney voice wound up being once again different upon his return.
