Open Mouth Insert Foot

I just had a short conversation that ended up not going too well.
I saw an advertisement at church that said "Disneyland 4 day Park Hopper Pass, 1 person, 100 dollars."

I came in and told my co worker about it.
I said that it was a great deal, but who would want to go to Disneyland 4 days in a row? That would not be fun.
He then informed me that Disneyland is the place that him and is wife are going for their honeymoon next week.
oops.
