Some funny Halloween jokes for adults are "For Halloween I'm going to write "Life" on name tag and hand out lemons to strangers," "My husband is so ugly, on Halloween he went to ask the neighbors to turn down their TV and they gave him some candy," and "Vampire pick-up line: What's your type?" Halloween jokes may be appropriate for adults because they are risqué, deal with relationships, are graphic or deal with topics that don't interest children.
Some Halloween humor takes the form of riddles. Examples include, "Which ghost is the best dancer? The Boogie Man!" and "What do you call a hot dog with nothing inside it? A hollow-weenie!"
Other jokes are more appropriate for adults because children would not relate to the subject matter. These slice-of-life jokes include, "Thank God for Halloween! Now I can call all the cobwebs in my house decorations," and "I visited a real graveyard this Halloween. I signed on to Google Plus."
Many jokes for grown-ups deal with dating and relationships. An example of this type of humor is, "One monster said to another, 'That lady just rolled her eyes at me. What should I do?' And the other monster replied, 'Be a gentleman. Roll them back.'"
