He used a remote control car and his Turbo Man suit as a weapon in Jingle All the Way. Also in the Santa warehouse I believe he tried to hit the giant Santa with some kind of weapon, then followed up to use a midget to throw at the other santa, it's kind of scary I remember this. Actually I'm not going to kid anyone, Jingle All the Way rules. "PUT THAT COOKIE DOWN....NOW!"
I think Junior may be the only movie he's never used a weapon.
I wouldn't count his cameos either, Dr. Doolittle 2 and The Rundown, because that's just stupid.
You're just a cook...
