Stoping Puns

Wife: How? Me: Self control

Since you guys enjoyed my dad moment in math class I thought I'd share my chemistry moment too.

So we are discussing atmospheric pressure and my teacher thought it be a good example to ask us to stand up to example how we can overcome the pressure. So everyone is standing and I remain sitting,

Teacher: so what's stoping you from standing up?

Me: Peer pressure
