He does the T thing on purpose sometimes he forgets and pronounces it properly as th it’s been years since I watched/listened to him because I find him so fake and annoying but I remember noticing this a few times Anna was veryJonny Rotten Tooth can't pronounce "th". .... "today is September turd, friendliest friends, what do you tink we should do!"
Is it because of his rabbit teeth, poor education, or can the Irish just not make the proper sound?
Irish sounding in the early days just like Erica but she puts on the American accent probably picks it up from watching American youtubers there are a few that follow her I notice with my younger grandbairns who sound American from watching so much American YouTube my friend is a teacher and they have picked up on this in school !!
