Warning, this one might be considered slightly blue:

On the first date with my present wife we were at the bar of a well-known restaurant in Marco Island, FL and were served up a couple of Hurricanes with a float of strong rum on the top and she said "oh boy, how do you hold your liquor?" and as I started to imbibe I thought, but didn't say "by the ears". Good thing I didn't have a big swallow going down or there would have been a ballistic nasal spew. After we became a couple I told her of this and scored points for my gentlemanly restraint.
