"Er" pronounced as "Oi"

From Homestar Runner Wiki

In a few of his Emails, Strong Bad pronounces an "er" sound as an "oi" sound. This is probably parodying Brooklyn accents. Incidentally, Coach Z's and The Wheelchair's accents often causes the inverse to happen, e.g., "terlet" or "berled cabbage".
