Bert and? Bert and? Bert and? Ernie, duh. You can’t have Bert without Ernie. The introvert needs the extrovert. The sweater with vertical stripes needs the sweater with horizontal stripes. The community needs the compassionate energy partner. Well, actually, hold onto that one for a second.
There’s a particularly touching episode of Sesame Street where Ernie has bread for lunch and Bert has peanut butter. Alone, neither option is appetizing. But then, epiphany. Bert and Ernie join forces to enjoy yummy sandwiches instead.
