Romeo and Juliet, v. 3.

Juliet. Drink all, and leave no friendly drop,

To help me after?—I will kiss thy lips;

Haply, some poison yet doth hang on them,

To make me die with a restorative.

Romeo and Juliet, v. 3.

Alas, poor Yorick!... Here hung those lips that I have kissed I know not how oft.

Hamlet, v. 1.
