Bruce Wayne made like Bruce Jenner this weekend, as Batman took home the boxoffice gold yet again.

Sony's stoner comedy "Pineapple Express" couldn't cop the session's top berth, despite a heady $40.5 million in estimated domestic grosses since bowing Wednesday. Midweek binging sapped its Friday-Sunday strength, and the Seth Rogen-James Franco starrer had to settle for a silver medal with $22.4 million over a weekend seemingly influenced by Olympics telecasts.

The R-rated laffer's lighter-than-expected weekend tally allowed Warner Bros.' "The Dark Knight" to top domestic rankings for an incredible fourth straight frame, with the Batman sequel fetching another $26 million to pump cume to $441.5 million.

Third place on the weekend went to Universal's three-quel adventure pic "The Mummy: Tomb of the Dragon Emperor," which dropped a big 60% from opening grosses to register $16.1 million over its sophomore session and a 10-day cume of $70.7 million. Warners' female-skewing sequel "Sisterhood of the Traveling Pants 2" was fourth with $10.8 million in Friday-Sunday coin and $19.7 million since bowing Wednesday-- another front-loaded opening, suggesting some patrons hit theaters early in advance of the weekend's Olympics start.
