How many beers can a male drink before getting drunk?

There are many factors involved:

How big is the man? The bigger, the more he can drink without being impaired.

How fast? One beer an hour and I could never get drunk. One beer every half hour and it would take me about six hours to build up to the legal limit.

What type of beer? I can sit and drink most American Lagers all day (see above) and not get drunk, but two doppelbocks in less than an hour could put me over the limit.
