Fred McDade is Gru's hapless (and often clueless) next-door neighbor...who is quite often caught off-guard, yet is still never fully surprised, by the many unusual (and occasionally downright odd) happenings coming from his eccentric neighbor.  Gru's "dog", Kyle, often piddles on Fred's plants, something which Gru actively encourages.  Partially because he had enough of Fred's dog doing the same on his property, but also because Gru's just downright despicable.
