USS Hindenburg (also known as the bush administration
You do know that the Hindenburg D-LZ129 was a german Zeppelin, don't you?
Anyway, other bad names:
I.K.S. 4815162342 (the numbers from LOST, everything related to them was destroyed, why name a ship like that?)
U.S.S. Morning Glory (piloted by Era, kinda funny, but I just HAVE to kill him)
U.S.S. Toilet (seen it in Ker'rat, was my favorite target from then)
I.K.S. Pam'Anderson (The character's name is also Pamela Anderson and the char of this player is over 2m tall, seen him (not her, DEFINITELY him) on Ganalda Space Station several times)
U.S.S. Britney Spears, U.S.S. Harry Potter (definitely chosen to draw aggro in PvP)
And last but not least every version of ENTERPRISE:
Enterprise-A (with the letter attached to the name, instead of the letter field)
and so on. The same with character names like Jean-Luke Picard or JimTkirk. That's kinda creative to bypass the restrictions, but there are soooooooo many people flying around with names like that.
I also see the U.S.S. Exitprise quite often, but that's a quite cool name.
