The grocery store where Peter and Brian get the turkey, Highland Park Market, is an actual local chain that started in Manchester, CT. And it is shaped like a barn, as portrayed in the episode.
The cartoon character that comes in to perform the medical examination on Lois is Andy Capp, a permanently drunk, workshy husband to a long suffering wife Flo. The only error is his voice has a generic southern/London accent. Andy Capp is from Hartlepool - he should have a strong North Eastern English accent (the closest being the Geordie accent).
