It does get stuck in there. Just don't make the mistake of going out in public until it fades lol.
I had an NPC during a table top rpg session that was my excuse to do my foghorn leghorn voice. Spent all afternoon doing that voice, and couldn't stop when I made a beverage and snack run.
I already have a southern accent (technically a mountain accent, but that's quibbling), so hamming it up can get absurd lol
