That's actually pretty cool. Although, if by the time that happens Tobirama has gotten a bit "happy", then it's more likely that he'll change "SILENCE" for "NIGGA STFU OR IMMA KICK YO A$$" or such. Which would make them both laugh and wet their pants. That would be even more awesome.
Back on topic... In my Birthday, Her Majesty, The Sexiest Kunoichi From Konoha, Yamanaka Ino, HAS to be present. Hinata is also invited, she's a perfect woman. As friends, Kiba, Shino, Shikamaru and Naruto. Other guests would include definitely Jiraiya (RIP) and Tsunade. And of course, Your Excellency Hashirama, whitout whom laughing would not be considered laughing.
