Columbia students rallied yesterday to raise money for breast cancer research, and naturally, they came armed with funny t-shirts rife with sexual innuendo.

Of course, they’re not the first to pioneer this trend.

And so, here are some similar t-shirts you’ve might’ve seen over the years:

1. Good Boobs Are Worth Fighting For (Columbia Fundraiser)

2. Protect the Skin You’re In (Victoria Beckham Marc Jacobs Cancer T-shirt)

3. Save 2nd Base (Pink University)

4. Save the TaTas

5. Squeeze a Boob Save a Life

6. No They’re Not Real (But They’re Spectacular)

7. I Touch Myself

8. Go Ahead Touch 'Em
