I remember a family Christmas gathering where the parents ask me and "cousin Steve" [1] to sing "Joy to the World". They of course meant the Christmas carol. We looked at each other and started singing the hit song instead. We later sang the desired song.

[1] Steve isn't actually related, but our moms were best friends, we were in the same age and grade, and there was enough resemblance that everyone believed we were lying when we denied being related.
