Your Engineer Achievement Ideas Go Here

Just post what you'd put as an Engineer achievement were you in charge of such...Idea repeats are fine as long as they have different names.
Here's some I thought of:

Do Not Stand on the Operational End of the Device: Get a telekill.

Do Not Submerge the Device in Water; Even Partially: Destroy an enemy building that's in water.

Water Works: Get 5 kills with Underwater Sentries.

Improvisational Medicine: Heal 10,000 using Dispensers.

United League of Builders: Use 10,000 metal on Allied Buildings. (not yours)

Remodeling: Critwrench a Spy in the face.

So, who else has some achievements on their mind?

I had a thread like this... ;_;

Big Things Come In Little Packages: Kill 5 eneimies with one Level 1 sentry (would promote assualt engies)

Monkey Wrench: Kill 50 spies with the wrench.

Troop Transport: Have one pair of teleporters used 20 times without being sapped or destroyed.

Safety Zone: Shoot a total of 50 sticky bombs that are in midair.

How Did You Get In Here: Have a teammate telefrag an enemy through your teleporter.

You can shoot stickies in midair? :|

...I think.

You can bat them away. Good idea for a Scout achieve

Either way-

Spy sappin' my crit wrench - Crit and kill 5 spies with your wrench

Mah sentry - Fix your sentry whilst it takes fire from 2 different people at once (Medics unincluded)

Take it like a man, son - Wrench-kill 20 Scouts

Spy Sapping Mah- Wait, Never Mind - Remove 1000 Sappers.

True Repairman- Repair a total of 1000000 building health points.

Look guys, I have an IQ now!: Use the rotation button on a teleporter.

I told you to stop touching! - Kill 50 spys who sap one of your buildings.

Size dose matter! - Kill 5 Heavies with a single fully upgraded sentry gun without being destroyed.

Size doesn't matter (sometimes)! - Have a level one sentry kill 5 people without being destroyed.

Now that's just silly... - Kill a Sniper shooting your sentry, with your pistol, when said sniper is out of range of your sentry, when you are in vicinity of your sentry.

Friends Forever - Spend a round where all of your metal is used on buildings built by other Engineers.

Look at 'em go! - Have your sentry destroy another sentry.

Boys, there's a Spy 'round hear - Succesfully call Spy on an enemy Spy, and proceed to kill them 3 times.

These Goggles ain't just for show - Kill a Sniper with your Pistol from at least 20 feet (or from 2fort battlement to battlement, whichever's closer)

You can't touch this, son - keep a Level 3 Sentry alive for either a whole round, or for 20 minutes.

A little help for yer 'woman' - Help a Heavy kill 5 people with a Dispenser.

Successfully call spy? As in use the little voice command things? I always use my mic.
