Wasn't expecting this to happen! O.O

These three clips were all recorded from the same session. The achievements I got (in the order I got them):

The Argyle Sap- Blow up an Engineer, his Sentry, and his Dispenser with one sticky bomb detonation
He Who Celt It- Use your stickybomb launcher to kill an enemy player via environmental damage (In this case, my stickies launched the Pyro up into the air, and damaged him enough to kill him when he came crashing back down to Earth XD)
Loch Ness Bombster- Kill an enemy player with sticky bombs within 5 seconds of him teleporting
