Happy Birthday, dear...
I was at a comedy show in Oz, the comedian told a funny story about a dwarf. Suddenly a dwarf shouts up from the audience, something about it not being funny. To give the comedian his due, he said he didn't see him down there - to much amusement (to me anyway). The dwarf replied that it was his birthday and he had spoilt it.
The comedian feeling a little guilty now then proceeds to get everyone in the audience to sing happy birthday to him. The only thing is, no-one knew the little guy's name, so when everyone got to the line they simply sang, "Happy Birthday, dear....dwarf!..."
Ha ha. Maybe you had to be there.
