The One With Frank Jr. - S3-E5
[After Joey's just drilled through a wall very close to Chandler's head, Chandler runs into the living room.]
Joey: Oh, did I get you?
Chandler: No, you didn't get me! It's an electric drill! You get me, you kill me!
Answer: Usually by the seventh night of Hanukkah you don't know what to get the other person, and you will probably resort to getting the other person something insignificant. Chandler is basically saying that the pen is a stupid gift.
