The easiest guitar tab so far?

Hi everyone,
Found this Happy Birthday guitar tab,which could possibly be the easiest guitar tab I have so far come across.
Yep! Happy Birthday.
Using just three strings,I quote:-
'Actually a guitar tab staff normally has six lines for the six strings on the guitar but we will only use the three first strings to play this melody.'
Yes I know its a bit ...err basic but if it someones birthday,wouldn't be great to just pick up the guitar and play it.
