the way i could see it plan out:
1. have the paint brush equiped
2. build any level sentry and do the taunt
3. then (voice line plays), it will smack the sentry mulitiple times (like the meme), it will shoot the direction you want it (as like a rangular) for 5 seconds with using the metal on you not currently equiped in the sentry, (ending voice line e.g. "all better now") and back to normal.
so what you guys think...its good right?
