" from the wall and thrust his maids to the wall.\n"

" Ben. Part, fools! [Beats down their swords.]\n"

" Cap. What noise is this? Give me my long sword, ho!\n"
"\n"
" Wife. A crutch, a crutch! Why call you for a sword?\n"
"\n"
" Cap. My sword, I say! Old Montague is come\n"
" And flourishes his blade in spite of me.\n"

" Enter Old Montague and his Wife.\n"
