Lt. Harryhausen Undead Detective hashtag

Some of my colleague's, or perhaps they are just the voices in my head, are saying #LieutenantHarryhausenUndeadDetective is absurdly long. Suggestions such as #LtHarryhausenUndeadDetective or even the double entendre laden #TheUndeadDick have been tossed about. I hate to lose the Harryhausen pinache but understand that's a mouthful. What do you fine folks think? Are these hashtags too large for #Twitter & #Instagram ?
