It's Always Sunny in Philadelphia has been one of the most successful TV series of his career. 

He was born in Philadelphia like the character Mac he played in the TV series It's Always Sunny in Philadelphia. None of the other characters were originally born in Philadelphia. 

It took Rob 11 months to write the first 15 episodes of IASIP. Before his big break in 'It's Always Sunny in Philadelphia' he worked as a waiter at the restaurants part time. He continued to be a waiter even during the first season.

Weight gain & weight loss: During the 7th season of It's Always Sunny in Philadelphia, Rob gained 60 pounds in four months to make his character look funnier, he initially wanted to do 100 lbs but his doctor advised to limit it to 60, he tried to eat lot of healthy foods but that did not help, he consumed donuts, weight gain drinks, protein shakes to put on weights, he however on feedback of his friends decided to reduce back to normal, he lost 23 pounds within the next month.

His opinions on his own show: Rob believes 'It's Always Sunny in Philadelphia' should not be the mainstream idea of funny in a healthy society. The show according to him is an attempt to not be too uptight and be liberal in extracting comedy which is otherwise neglected by mainstream.

Inspiration behind creation of It's always sunny in Philadelphia: Desperation to find a job and make it big in Hollywood. (According to him)
