Irving was originally voiced by Chris Parnell in this pilot. But in the TV series, Scott Adsit took over.
He is implied to be a terrible cook in "The Finger" when Miriam Beaks mentions this by saying she really has no clue if his food is "food". He also caused a little fire thanks to his Casserole 5000.
As shown in "The Almighty Foo", Irving likely has entomophobia, or the fear of more than one class of insects. However, he does not want to see bugs killed despite his obvious fear.
He is the keytar player and founder of his band, "The Sillies."
In Recipe for Disaster Irving from lack of food, starts to get shakes and Miriam reminds him of his blood sugar, hinting he may be a diabetic.
