What is your favorite scene of Night at the museum movies ?

When the monkey steals his keys :)

my favorite scene in the movie night at the museum is the scene where the two small people come back after their revolving car crash. i love them very much. even though they are small, they are the most essential part in the movie. my most favorite scene in the movie night at the museum 2 is when the mighty Octavius wearing old army suit come in riding the squirrel. i love the dialog he says,"hold, the mighty Octavius has returned, i ride on the nature's most fearsome creature, i ride the squirrel"
