So out with a friend and some of his work colleagues. We get onto the topic of donating sperm and my friend makes the comment "i have great sperm" which we all find amusing and becomes a bit of a running joke. Anyway end of the night and were leaving and saying goodbye to his female colleagues and one says to me "you have great sperm" as a joke to which i reply "yes i do. You should taste it sometime"

complete silence.

So anyone else amde jokes in a public setting which have completely flopped?
