I came home really drunk

I came home really drunk last night and my wife wasn’t happy at all.

“How much have you had to drink?” she asked sternly, staring at me.

“Nothing” I slurred. “Look at me!” she shouted. “It’s either me or the pub, which one is it?” I paused for a second while I thought and mumbled…
“It’s you. I can tell by the voice.”
