You have no idea what it's like to hear people talk like this all the time.

"Other marked characteristics of Newfoundland English include the loss of dental fricatives (voiced and voiceless th sounds) in many varieties of the dialect (as in many other nonstandard varieties of English); they are usually replaced with the closest voiced or voiceless alveolar stop (t or d). The dialect also includes nonstandard or innovative features in verb conjugation. In many varieties, the third-person singular inflection is generalized to a present tense marker; for example, the verb "to like" is conjugated I likes, you likes, he/she/it likes, we likes, you likes, and they likes. (And in some communities on the island's northeast coast, you (singular), you (plural), and they become dee, ye, and dey, respectively.)"
