This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

A similar example related to that question would be "I watched T.V." but my question is specially about the event happened 'last night'. – user143212 Aug 24 '12 at 18:54

When a clause contains a specific past time reference, such as last night, the normal verb form is the past tense.
