Velcro Rip-Off

Listen up, buttercup! This joke is all about wordplay. Velcro is a fastener that you "rip" open. The joke says it's a "rip-off" which means it's overpriced or a scam. But here, it also plays on the literal ripping sound and action of using Velcro. It's like saying the quiet part out loud, which is funny because you're probably still using dial-up, aren't ya?
