AMY GARBER: Ew, bugs.
Getting bit or stung by one
can ruin a family barbecue
quicker than your drunk uncle
talking politics.
Right now in super duper
closeup, we'll find out how
something so tiny
can be so annoying.
I'm talking about bug bites, not
your uncle.
[OMINOUS MUSIC PLAYING]
[BUZZING]
First stop, the bee.
There it is piercing the skin
with its stinger.
Ouch.
Then it flies off, leaving
the stinger and a tiny venomous
sac behind.
Uh, rude if you ask me.
Anyway, a war is being waged
between that sac and your body.
The sac releases its venom.
And in response, your body
dispatches white blood cells
to fight it.
Next up, the mosquito.
As we all know, they bite you
to feed on your blood.
They're
like the "Twilight" vampires
without the sexy abs.
Mm.
[OMINOUS MUSIC PLAYING]
[BUZZING]
The mosquito uses its mouth
parts to pierce the skin.
At this very moment,
the mosquito's saliva
is thinning the blood so it
won't clot while she feeds.
Her saliva also causes
that annoying itchiness.
Now, only female mosquitoes bite
you.
They need the blood for egg
production.
[SLURPING]
And there she goes, sucking down
that blood faster
than your uncle sucks down cans
of affordably-priced light beer.
[BURP]
There are hundreds
of other kinds of bug bites
I could get into, including some
that are deadly.
Unfortunately, I can't show you
those without putting someone's
life in danger.
I'd gladly let my uncle get bit
by a spider, but our lawyers
won't let me.
Not my rules.
[BUZZING]
Ow.
Where'd that come from?
