Enough with the rambling. I WANNA KNOW WHAT SHAKESPEARIAN PLAY TYBALT IS 
FROM!!! Really, it's been bugging me all day. I tried to look it up, but 
I couldn't find my copy of his complete works. (I have it somewhere, but 
I just don' know where.) This is so ironic too, cause I've read most of 
his plays. I've even performed in them a few times. Once I even wrote a 
satire of one his plays. (The Merchant Of Venice: Part 2: Shylock's True 
Love - Prune Juice.) Anyhow, please, I beg of you! Someone tell me what 
play Tybalt is from... Please...
