Bad Breath?!

i always think to myself, since Paul and George always were singing at the same mic during performances, how would Paul feel if George had bad breath? haha xD or the other way around! i have a perfect pic for this.

are they trying to eat each other or what? paul seems to be delighted but George looks upset. i think its safe to say that maybe this time, it was paul who had too many onions xD ha ha
