Poor old lady, she swallowed a fly. I don’t know why she swallowed a fly. Poor old lady, I think she’ll die. Poor old lady, she swallowed a spider. It squirmed and wriggled and turned inside her. She swallowed the spider to catch the fly. I don’t know why she swallowed a fly. Poor old lady, I think she’ll die. Poor old lady, she swallowed a bird. How absurd! She swallowed a bird. She swallowed the bird to catch the spider, She swallowed the spider to catch the fly, I don’t know why she swallowed a fly. Poor old lady, I think she’ll die. Poor old lady, she swallowed a cat. Think of that! She swallowed a cat. She swallowed the cat to catch the bird. She swallowed the bird to catch the spider. She swallowed the spider to catch the fly, I don’t know why she swallowed a fly. Poor old lady, I think she’ll die. I am normal, don't judge me.
I went to manilla, where I had icecream that was vanilla, the vibe it gave me was so killer, that i ran into a pillar, ouch.
