Perhaps remotely related to the "phono bomb" discussion...
Back in the 1970s, as a graduate student studying computer/electronic music, we had quite a few tapes in our lab that we could use for demonstration purposes when doing lectures. This was in the days before we had easy means to sample sounds, yet one tape featured a dog barking "Tea for Two." I have never encountered that recording again and wonder if the mention of it rings a bell with anyone. I still remember finding it very funny.
