text: Many Ernie and Bert sketches involve Ernie wanting to play a game with Bert , who would much rather do something else ( like read ) . Ernie keeps annoying Bert with the game until Bert joins in â `` and usually , by the time Bert starts enjoying the game , Ernie is tired of playing the game and wants to do something else .
simplified: Bert is Ernie 's brother and roomate .
