Also, I have a t-shirt that says "The Beatles are coming!" -- yes, "are coming", as in, present tense -- and I just live for the reactions I get while wearing it. XD
I often catch people doing a confused double-take, but, unless they know me, they often don't say anything.
Occasionally, people at least work up the courage to say something like, "Uh, I mean... they came... and they were very successful, but, uh..."
But by far the best reaction I've gotten so far, was when my roommate and I were quietly eating lunch together, and all of a sudden they looked over to me and said -- "Listen... I don't think the Beatles are coming. I mean, two of them are dead, it's time to face facts."
That fucking killed me. XD
