However, the depth of Jerry and Newman's enmity seems to vary between episodes — or even within the same episode ("The Soul Mate") — and Jerry sometimes seems to consider him merely an annoying neighbor, rather than an outright enemy. Occasionally events lead one of them ("The Blood"), or both ("The Soup Nazi"), to briefly forget their differences and at times even work together on some scheme, such as in "The Shower Head" when they join together with Kramer to buy black market non-water-saving shower heads. In "The Old Man", Jerry casually mentions "a couple of friends", referring to Kramer and Newman. Jerry and Newman also attend Super Bowl XXIX together, but only because of a ticket mix-up. In "The Label Maker", Jerry reluctantly agrees with George that Newman is "merry", which appeared to be a compliment of sorts.
