I’m a big fan of Zojirushi’s mugs. You’ll need a bottle brush to clean, but I think all their gaskets are removable and replaceable. I’ve never had a problem with leaks and they have a solid sliding lock.

This is why in The Simpson you will see David S. Cohen and in Futurama he is David X. Cohen. I think in a Futurama commentary he told about confusion in a guild or royalty payments that made him change how he was credited.
